Which Old Testament? The Septuagint, the Masoretic, and the Verses That Settle It

I. Introduction — One Honest Question

The full Hebrew text of the Old Testament — the Masoretic Text (MT) — comes to us in two great codices: the Aleppo Codex (c. AD 930) and the Leningrad Codex (AD 1008). Both were copied roughly nine centuries after the resurrection. The Septuagint (LXX), the Greek translation of the Hebrew Bible used across the Greek-speaking Jewish world of antiquity, was rendered in the third to second centuries BC. The Dead Sea Scrolls — Hebrew, Aramaic, and Greek manuscripts found at Qumran and the surrounding sites — date roughly from 250 BC to AD 70. Both the LXX and the Scrolls are pre-Christian.

That gap is the honest question. The divisive event between what would become Judaism and what would become Christianity was the coming of Christ. If our complete Hebrew Old Testament reaches us in copies a thousand years after his coming, while our oldest complete Greek translation predates him, how do we know the Hebrew copyists who preserved the MT through the rabbinic centuries did not quietly rewrite it — softening passages the Christians claimed for Jesus, removing words that pointed too plainly to him?

The question is not whether the Hebrew Bible that Jesus and the apostles read was authoritative. It was. The question is whether the Hebrew Bible we have today, preserved by Jewish scribes through the centuries after the divisive arrival of Christ, still reads as the Hebrew Bible they knew. The only honest way to answer the question is to look at the surviving Hebrew text from before Christ, and at the most important pre-Christian translation made from a Hebrew Vorlage now lost.

Four lines of evidence run the test.

First, the Dead Sea Scrolls themselves. They predate the Masoretes by roughly seven hundred years, and they predate the resurrection by up to three centuries. They contain large portions of every book of the Hebrew Bible except Esther. They give us a direct window onto the Hebrew text in circulation before and during the apostolic generation.

Second, the Septuagint. Its Hebrew Vorlage no longer survives, but the translation does, and the Greek bears witness — sometimes faithfully, sometimes interpretively — to the Hebrew copies in the hands of third- and second-century BC Jewish translators in Alexandria.

Third, the Samaritan Pentateuch. The Samaritan community split from mainstream Judaism in the centuries before Christ and has transmitted its own Hebrew Torah independently ever since. Its textual tradition is pre-Christ; its readings cannot have been influenced by post-Christian rabbinic editing. For the five books of Moses, the Samaritan Pentateuch is a second independent pre-Christ Hebrew witness — where it agrees with the MT, two unrelated Hebrew transmission lines both predating Christ converge on the same reading.

Fourth, the apostolic citation record. The New Testament authors quote the Old Testament repeatedly. The text-form they quote shows what Hebrew and Greek Old Testament stood in their hands in the first century AD — before the parting of synagogue and church hardened, and before any later scribal tradition could have done its work.

The thesis this study will defend is plain.

The MT we have at c. AD 900 is not a Christian-era rewrite. The Great Isaiah Scroll (1QIsaᵃ, c. 150–100 BC) is approximately 95% identical to the Masoretic Isaiah — meaning the proto-Masoretic tradition was already stable two centuries before Christ, and the Masoretes did not alter the text but conserved it across the thousand years of transmission to the medieval codices. Where the LXX preserves a reading the MT lacks (Isa 53:11's "light"; Deu 32:43's longer cola; Psa 22:16's verb of piercing), the Dead Sea Scrolls often confirm that the LXX is translating a real pre-Christian Hebrew Vorlage — meaning some pre-Christian Hebrew manuscripts had readings the proto-MT did not. This is Hebrew textual diversity in the Second Temple period, not Masoretic forgery in the rabbinic one.

Eight specific passages are usually offered as the test cases — places where, on the surface, the MT and the LXX read differently and where the question of "did the rabbis alter the Hebrew" is most often pressed: Psalm 22:16, Psalm 40:6, Deuteronomy 32:43, Amos 9:12, Isaiah 53:11, Isaiah 7:14, Isaiah 42:4, and Zechariah 12:10. The article walks each in turn. One of them — Zechariah 12:10 — settles a tightly-related question: which Hebrew Vorlage of that verse stood in the hands of the apostles. The verb the apostles use at Jhn 19:37 and Rev 1:7 is G1574 ἐκκεντέω, the standard Greek equivalent of the Hebrew H1856 דָּקַר ("pierce") — the verb the MT preserves, and the verb the LXX Zechariah translator alone (against every other LXX translator) replaced with κατωρχήσαντο ("mocked"). The apostles' Hebrew at Zec 12:10 agrees with the proto-MT, not with the LXX. The pierced-Messiah verse — the most Christologically charged single verb in the prophets — already stood in the apostolic generation in the form the MT later set down at AD 900.

This is a text-critical and lexical study. The voice that follows is exact. Every claim cites the verse, the Strong's number, the morphological form, or the manuscript witness. Where the text is clear, the article will be clear; where the manuscript evidence is mixed, the article will say so.

II. The Eight Variants — Where the MT and the LXX Differ

The eight passages most commonly raised as evidence that the Hebrew text was altered, or as grounds for preferring the LXX wholesale, are these:

1. Psalm 22:16 — MT "like a lion" vs. LXX "they pierced"
2. Psalm 40:6 — MT "ears you have opened" vs. LXX "a body you have prepared" (cited at Heb 10:5)
3. Deuteronomy 32:43 — MT short form vs. LXX long form with "let all the angels of God worship him" (cited at Heb 1:6)
4. Amos 9:12 — MT "remnant of Edom" vs. LXX "remnant of mankind" (cited at Act 15:17)
5. Isaiah 53:11 — MT "he will see, be satisfied" vs. LXX "he will see light"
6. Isaiah 7:14 — MT עַלְמָה (ʿalmāh, young woman) vs. LXX παρθένος (parthenos, virgin) (cited at Mat 1:23)
7. Isaiah 42:4 — MT "islands wait for his Torah" vs. LXX "in his name nations will hope" (cited at Mat 12:21)
8. Zechariah 12:10 — MT "they pierced" vs. LXX "they mocked" (cited at Jhn 19:37 and Rev 1:7)

The table below sets each of the eight side by side with the original Hebrew, the LXX Greek, the Strong's numbers, and a verdict on the kind of shift the LXX made. Preserved means the LXX renders the Hebrew faithfully into Greek (with whatever transitional idiom Greek requires). Softened means the LXX weakens or generalizes the Hebrew. Reinterpreted means the LXX moves the Hebrew into a different semantic field altogether. The verdicts rest on the lexical evidence in the manuscript record, not on theological preference.

The pattern that emerges is mixed and instructive. Six of the eight rows show the LXX preserving or sharpening the Hebrew sense; in those rows, where a NT author cites the verse, he follows the LXX form (Acts 15:17 → Amos 9:12; Hebrews 1:6 → Deuteronomy 32:43; Hebrews 10:5 → Psalm 40:6, with one further adaptation; Matthew 1:23 → Isaiah 7:14; Matthew 12:21 → Isaiah 42:4). Two of the eight rows show the LXX reinterpreting the Hebrew into a different semantic field. Of those two, the apostolic record splits clean down the middle. Matthew embraces the LXX's reinterpretation at Isaiah 42:4 and quotes it word-for-word in Mat 12:21. John and the Seer reject the LXX's reinterpretation at Zechariah 12:10 and translate the Hebrew themselves at Jhn 19:37 and Rev 1:7.

That split is the article. The next section works it out.

III. The Decisive Case — Zechariah 12:10

III.A — The MT and LXX Side by Side

The Hebrew of Zechariah 12:10 reads:

וְהִבִּ֥יטוּ אֵלַ֖י אֵ֣ת אֲשֶׁר־דָּקָ֑רוּ וְסָפְד֣וּ עָלָ֗יו

wĕhibbîṭû ʾēlay ʾēt ʾăšer-dāqārû wĕsāfĕdû ʿālāyw

"and they will look to me, the one whom they pierced, and they will mourn for him" (Zec 12:10)

The verb at the centre of the verse is דָּקָרוּ (H1856 דָּקַר dāqar) in the Qal perfect 3rd common plural — "they pierced." Note in passing the prophetic pronoun shift: the speaker is Yahweh ("they will look to me, whom they pierced") and the mourning that follows is for a third-person ("they will mourn for him"). That oscillation between first and third person is a feature of the divine oracle, where the figure pierced and the figure mourned cannot be cleanly separated from Yahweh himself. It is the same kind of grammatical tension that drives the Christological reading the apostles would later make.

The verb H1856 דָּקַר is unambiguously a verb of physical piercing. It appears in the canonical Old Testament eleven times across ten verses (1 Sam 31:4 contains two forms). The roster is uniform:

• Num 25:8 — Phinehas thrusts his spear through the Israelite man and the Midianite woman
• Jdg 9:54 — Abimelech orders his armour-bearer to run him through with his sword
• 1Sa 31:4 — Saul asks his armour-bearer to pierce him on Gilboa
• 1Ch 10:4 — the Chronicler retells the same Saul narrative
• Isa 13:15 — every one found will be thrust through (in the oracle against Babylon)
• Jer 37:10 (LXX Jer 44:10) — pierced Chaldeans
• Jer 51:4 — pierced in her streets
• Lam 4:9 — those pierced by the sword are better than those slain by hunger
• Zec 12:10 — the verse before us
• Zec 13:3 — the parents of a false prophet pierce him through

In every one of those passages the verb means to thrust a sharp object through a body. There is no metaphorical use, no mockery use, no derived sense of derision. The Hebrew is unambiguous.

The LXX of the same verse reads:

καὶ ἐπιβλέψονται πρός με ἀνθ᾿ ὧν κατωρχήσαντο καὶ κόψονται ἐπ᾿ αὐτὸν

"and they will look toward me, instead of whom they mocked, and they will mourn over him" (LXX Zec 12:10)

The verb the LXX Zechariah translator chose is κατορχέομαι (not assigned a Strong's number in the standard NT-keyed concordances; aorist middle 3pl form κατωρχήσαντο) — "to dance over a fallen one, to triumph over, to mock." It is not a piercing verb at all. The central image of Zechariah's vision — a divine figure pierced — has gone missing in the Greek.

Two apostolic witnesses cite this verse. Both reject the LXX's verb. John, recording the moment of the spear-thrust at the cross, writes:

ὄψονται εἰς ὃν ἐξεκέντησαν

"they will look on the one whom they pierced" (Jhn 19:37)

And the Seer, opening the Apocalypse with the announcement of Christ's return:

οἵτινες αὐτὸν ἐξεκέντησαν

"those who pierced him" (Rev 1:7)

Both use the same Greek verb: G1574 ἐκκεντέω, "to pierce through." Neither uses the LXX Zechariah's κατωρχήσαντο. The two apostolic citations agree against the Greek translation that was, by the first century, the most widely circulated Old Testament in the Mediterranean world.

III.B — The dakar / ekkenteo Bridge

The lexical case for what John and the Seer did is straightforward. In Greek translation work, when the same Hebrew verb appears across multiple Old Testament books, the LXX translators usually settle on a standard equivalent — a default Greek verb that signals to a Greek reader, "this is the Hebrew word dāqar." The standard equivalent of H1856 דָּקַר is G1574 ἐκκεντέω. This is not a guess. Abbott-Smith's Manual Greek Lexicon of the New Testament states the equivalence explicitly under G1574: "in LXX chiefly for דָּקַר."

The canonical occurrences confirm what the lexicon says. Trace H1856 across the Hebrew Bible and look at what each LXX translator did, and the pattern is uniform — except at LXX Zec 12:10.

Read the table line by line and the conclusion is forced. Two apostolic authors, writing independently — one in a Gospel, the other in an apocalyptic vision — both translated דָּקַר correctly into Greek using the verb the LXX itself uses for that Hebrew root everywhere else. They went past the LXX Zechariah form. They restored the equivalence the LXX had broken.

Two further confirmations from the manuscript record. First, the numerical: a direct lexical comparison of John 19:37 with LXX Zec 12:10 shows only 22% shared distinct Greek terms, and the shared terms are common particles — G2532 καί ("and") and G3739 ὅς ("which"). There is no substantive shared vocabulary between John 19:37 and the LXX of Zechariah 12:10. Second, the structural: when Jhn 19:37 is checked for textual similarity against the entire Greek Old Testament corpus, Zechariah 12:10 does not appear among the close matches. If John had been quoting the LXX of Zechariah, his Greek would match the LXX Greek closely enough to surface at high rank. It does not — because he was not.

This is the verse that breaks the "wholesale LXX" claim. The LXX is not a uniform witness to the Hebrew. The LXX Zechariah translator, for whatever reason — perhaps an interpretive embarrassment at the image of a pierced Yahweh, perhaps a textual variant in his Hebrew Vorlage — departed from the standard equivalence. Two apostles, holding the inspired pen, restored it. The Hebrew won — and it won in the form the MT later preserved.

There is a third confirmation in the manuscript record. The pre-Christ Hebrew at Zechariah 12:10 is preserved at Qumran in 4Q80 (4QXIIᵉ), the Qumran Twelve Prophets manuscript. The fragment reads:

[ושפכתי על] בית דויד [ועל יושב ירושלים רוח חן ותחנונים והביטו אלי את אשר ד]ק̇רו וספדו̇ [עליו]

"[and I will pour out on] the house of David [and on the inhabitants of Jerusalem a spirit of grace and supplications, and they will look to me, the one whom they] pi̇erced and they shall mourn [for him]" (4Q80 at Zec 12:10; brackets mark text reconstructed from context)

The verb is the same root דקר that the MT preserves. Two apostles, John in his Gospel and John in the Apocalypse, render this Hebrew verb with G1574 ἐκκεντέω — the standard LXX equivalent of דקר that the LXX Zechariah translator alone broke. The apostles' Hebrew Vorlage at Zec 12:10 matches both the proto-Masoretic Hebrew preserved in the AD 900 codices and the pre-Christ Hebrew preserved at Qumran. The pierced-Messiah verse stood in this form before Christ; it stood in this form in apostolic hands; and it stood in this form when the Masoretes set down the Hebrew Bible a millennium later. There is no place for a post-Christian rabbinic alteration in that transmission chain.

The claim that "the apostles used the LXX, not the MT" cannot survive Zechariah 12:10. At the most Christologically charged single verb in the prophets — the verb that points to Calvary itself — the apostles read the Hebrew reading the proto-MT carried, not the Greek translation of it. The doctoring charge is triply answered: the pre-Christ Hebrew at Qumran reads "they pierced," the apostles' Greek translates "they pierced," and the MT at AD 900 preserves "they pierced." Three independent witnesses across a millennium of transmission converge on the same Hebrew reading. None of them required a Masoretic invention.

IV. The Apostolic Citation Scoreboard

To test the apostolic record across more than one verse, twelve representative NT-OT citations were compared against their LXX and MT source passages. The method is direct. For each citation, the percentage of distinct Strong's-tagged terms in the NT verse that also appear in the LXX source passage is measured. Greek-to-Greek (a NT verse against the LXX of its OT source) yields a meaningful number, because both texts share the same Strong's pool. Greek-to-Hebrew (a NT verse against the MT) registers as zero by structural necessity — different languages, different Strong's pools — so the absolute MT figure is not the diagnostic. What tells the story is which text-form's semantic content the NT verse is following: which words it shares, which it omits, which it adds, and what theological move those choices make.

Walking through the scoreboard by category:

Seven citations follow the LXX. Acts 15:17 quotes Amos 9:12 at 79% Greek-to-Greek coverage — near-verbatim, with "remnant of mankind" instead of "Edom." Matthew 12:21 quotes Isaiah 42:4 at 71%, with "in his name the nations will hope" — the LXX's reinterpretation of the Hebrew Torah-and-islands clause. Matthew 2:18 quotes Jeremiah 31:15 at 68% — Rachel's lament. 1 Corinthians 15:55 quotes Hosea 13:14 at 67% — Paul's "O death, where is your sting?" uses G2759 κέντρον ("sting") which is in the LXX text but not in the MT Hebrew of Hos 13:14. Matthew 1:23 quotes Isaiah 7:14 at 58% with the LXX's παρθένος. Hebrews 10:5 quotes Psalm 40:6 at 47%, using the LXX's verb καταρτίζω, though adapting beyond the LXX's "ears." Hebrews 1:6 quotes Deuteronomy 32:43 at 33%, with the phrase "let all the angels of God worship him" — a phrase entirely absent from the MT and present in the LXX (and confirmed in the Hebrew Vorlage by 4QDeutq).

Three citations follow the MT semantically. John 19:37 and Revelation 1:7 cite Zechariah 12:10, both with G1574 ἐκκεντέω against the LXX's κατωρχήσαντο. Matthew 2:15 cites Hosea 11:1 with the singular τὸν υἱόν μου ("my son"), matching the MT's singular לִבְנִי (לִ-בֵּן with 1cs suffix, H1121 בֵּן) and not the LXX's plural τὰ τέκνα αὐτοῦ ("his children"). Matthew 8:17 cites Isaiah 53:4 with ἀσθενείας ἔλαβεν ("he took our weaknesses") — closer to the MT's H2483 חֳלִי ("disease, sickness") than to the LXX's ἁμαρτίας ("sins"). The LXX had spiritualized Isaiah's bodily idiom; Matthew kept it physical, because Matthew was reporting healings.

One mixed. Romans 11:4 cites 1 Kings 19:18 at 27% LXX coverage, but Paul's τῇ Βάαλ — with feminine article before "Baal" — matches neither the standard MT nor the standard LXX. The form looks like an eclectic Greek text-form not preserved in our manuscripts.

One LXX-aligned with apostolic adaptation. Hebrews 10:5 quotes Psalm 40:6 in clearly LXX form (the verb κατηρτίσω is the LXX's, not the MT's) — but then replaces ὠτία ("ears") with σῶμα ("body"). Three text-forms exist for this single verse: the MT ("ears you dug for me"), the LXX ("ears you prepared for me"), and Hebrews ("a body you prepared for me"). The author of Hebrews works from the LXX but adapts beyond it for his incarnational argument — that the body of Christ replaces the body of bulls and goats (Heb 10:5–10).

The scoreboard:

The most economical refutation of any "Matthew used only the LXX" claim sits within Matthew's own first two chapters. At Mat 1:23 he quotes the LXX's παρθένος from Isa 7:14 — the LXX's intensification of ʿalmāh into "virgin." One chapter later, at Mat 2:15, he quotes Hos 11:1 with the singular τὸν υἱόν μου — matching the MT's singular לִבְנִי, against the LXX's plural τὰ τέκνα αὐτοῦ ("his children"). Same evangelist. Same nativity cycle. Same πληρόω formula introducing each citation. Different text-forms. The text-form chosen depends on what the Spirit-directed argument requires: the LXX where it sharpens the sign, the MT where the singular Son is the sign. The notion that Matthew was a LXX-only writer collapses against his own pages.

The scoreboard does not say that the LXX is wrong and the MT right. It says that both witnesses were available to the apostles, and the apostles did not always pick one. The "wholesale-LXX" overreach is empirically false. The "MT-only" underreach — that the LXX has no apostolic standing — is also empirically false. The textual evidence is what it is.

V. The almah / parthenos Question

Of the eight variants, none has been more polemically argued than Isaiah 7:14. The Hebrew reads:

הִנֵּה הָעַלְמָה הָרָה וְיֹלֶדֶת בֵּן וְקָרָאת שְׁמוֹ עִמָּנוּ אֵל

hinnēh hāʿalmāh hārāh wĕyōledet bēn wĕqārāʾt šĕmô ʿimmānû ʾēl

"Behold, the young woman is pregnant and bears a son, and you will call his name Immanuel" (Isa 7:14)

The disputed word is הָעַלְמָה (H5959 ʿalmāh) with the definite article הָ ("the"). The LXX renders this ἡ παρθένος (G3933 parthenos, "the virgin"). Matthew 1:23 quotes the LXX form word-for-word: ἰδοὺ ἡ παρθένος ἐν γαστρὶ ἕξει καὶ τέξεται υἱόν ("Behold, the virgin shall conceive and bear a son").

The lexical question is what ʿalmāh actually means in Hebrew. The honest answer the canonical occurrences support is this: H5959 is an age-class word, not a technical virginity word. The technical Hebrew word for "virgin" is H1330 בְּתוּלָה (bĕtûlāh), which appears 50 times in the canonical Old Testament. H5959 ʿalmāh appears only 7 times. When the Old Testament needs to mean "virgin" in the strict sexual-status sense, it uses H1330 — and frequently adds an explicit gloss.

The proof is in Genesis 24, the chapter where the same narrator describes the same woman, Rebekah, with both words within the space of twenty-seven verses:

וְהַֽנַּעֲרָ֗ טֹבַ֤ת מַרְאֶה֙ מְאֹ֔ד בְּתוּלָ֕ה וְאִ֖ישׁ לֹ֣א יְדָעָ֑הּ

"and the young woman was very fair to look upon, a virgin (H1330), and no man had known her" (Gen 24:16)

Then, of the same Rebekah:

אַתֲּ הָעַלְמָה הַיֹּצֵאת לִשְׁאֹב

"the young woman (H5959 ʿalmāh) who comes out to draw water" (Gen 24:43)

Same chapter. Same woman. When the narrator wants to say "virgin" in the technical sense — that no man has known her — he uses H1330 bĕtûlāh and reinforces it with the explanatory gloss "and no man had known her." When he simply identifies Rebekah by social description — the marriageable girl drawing water at the well — he uses H5959 ʿalmāh, with no gloss attached. The two words operate in different lexical registers. ʿalmāh tracks age and social status (a marriageable young woman); bĕtûlāh tracks sexual status with explicit confirmation.

The full distribution of H5959 across the canon makes the same point.

The Greek word G3933 παρθένος normally translates the technical Hebrew virgin term H1330 bĕtûlāh. The LXX renders the looser H5959 ʿalmāh as παρθένος only twice in the entire Old Testament — at Gen 24:43, where Rebekah is contextually a virgin (the narrator just told us so in v. 16), and at Isa 7:14. The LXX choice at Isa 7:14 is exceptional within the LXX's own practice. The Greek translator of Isaiah interpreted the ʿalmāh in the sign-oracle as παρθένος — intensifying the sexual-purity nuance beyond what the Hebrew word, on its own, technically requires.

Three things are true here, each with its own weight.

The MT is what Isaiah wrote. ʿalmāh is the word Isaiah chose. The MT preserves the original. There is no textual basis for the claim that "the rabbis altered בְּתוּלָה into עַלְמָה" — the word ʿalmāh is in every ancient Hebrew witness to Isaiah 7:14, including the Great Isaiah Scroll (1QIsaᵃ).

The LXX made an interpretive choice. Rendering ʿalmāh as παρθένος is a legitimate but not mandatory translation. It captures the cultural assumption that an unmarried ʿalmāh would be a virgin — but it goes one step beyond what the Hebrew word, technically, asserts.

Matthew's citation is authoritative for Mat 1:23. Matthew quotes the LXX's παρθένος because the conception of Jesus by a Mary "before they came together" (Mat 1:18) and "until she had given birth to a son" without sexual relations (Mat 1:25) confirmed the παρθένος reading at the level of historical fulfillment. The Spirit-directed apostolic citation overrides the LXX-MT scholarly debate for that passage. Matthew is not claiming that ʿalmāh universally means "virgin"; he is claiming that the specific ʿalmāh of the Immanuel sign was a virgin, by the testimony of the historical event.

The accusation that "the MT was deliberately altered to remove παρθένος" inverts the actual textual situation. The MT preserves Isaiah's original word ʿalmāh. The LXX intensified that word. Matthew confirmed the intensification by historical fulfillment. Three witnesses, three valid roles, no fabrication required.

VI. The Dead Sea Scrolls Picture

The most serious form of the doctoring charge is the claim that the rabbis, in the centuries after the rise of Christianity, edited their Hebrew text to obscure passages that pointed to Jesus. The Dead Sea Scrolls let us test that charge directly. They date from c. 250 BC to AD 70. They predate the rabbinic Masoretes (c. AD 600–1000) by more than half a millennium, and the surviving complete MT codices (Aleppo c. AD 930, Leningrad AD 1008) by roughly a thousand years. Whatever the proto-MT looked like before AD 70 — before the parting that gave rise to the doctoring charge in the first place — the Scrolls show us.

The foundational fact is the Great Isaiah Scroll. 1QIsaᵃ, dated approximately 150–100 BC, contains the entire book of Isaiah. It is approximately 95% identical to the Masoretic Isaiah. Minor variants exist — orthographic differences, occasional word swaps — but no major theological alterations. The implication is direct: the proto-Masoretic tradition of Isaiah was already stable by the second century BC, and remained substantially unchanged across the seven hundred years until the Masoretes set it down. The Masoretes did not invent the MT; they conserved it.

That fact alone refutes the wholesale "deliberate alteration" claim. If the MT and 1QIsaᵃ agree at 95% across hundreds of years of transmission predating Christianity, the MT cannot be a Christian-era anti-Christian rewrite. Whatever the rabbinic scribes were doing during the centuries between Christ and the Masoretes, they were not freely revising the Hebrew of Isaiah — because 1QIsaᵃ, sitting in a cave at Qumran before Christ was born, already reads almost identically to the MT they would later set down.

A second pre-Christ Hebrew tradition reinforces this finding. The Samaritan Pentateuch (SP) is a Hebrew text-form of the Torah preserved by the Samaritan community, who split from mainstream Judaism in the centuries before Christ and have transmitted their own Hebrew Torah independently ever since. The Samaritan Pentateuch's textual tradition is therefore pre-Christ; its readings cannot have been influenced by post-Christian rabbinic editing. Where the SP and the MT agree on a Torah reading, that reading is attested by two independent Hebrew traditions that diverged before Christ — a doubly strong refutation of the doctoring charge for that verse.

The DSS evidence in the other direction — passages where the Scrolls confirm an LXX reading against the MT — is real, however, and an honest account must name it. The three test cases:

Isaiah 53:11. The MT reads only יִרְאֶה יִשְׂבָּע — "he will see, he will be satisfied" — with no stated object of "see." The LXX adds φῶς ("light"): δεῖξαι αὐτῷ φῶς ("to show him light"). Four independent Qumran Isaiah manuscripts preserve the longer Hebrew with אוֹר ("light") as the object of "see": 1QIsaᵃ (the Great Isaiah Scroll, c. 150–100 BC) reads מעמל נפשוה יראה אור וישבע — "from the labor of his soul he shall see light and be satisfied"; 1QIsaᵇ reads יראה אור יש[בע]; 4Q56 (4QIsaᵇ) and 4Q58 (4QIsaᵈ) confirm the same reading. The MT here is the outlier — a shorter Hebrew tradition that lost the word אוֹר. The LXX is translating a real Hebrew Vorlage that four pre-Christ Qumran manuscripts had preserved. This is the cleanest case in the eight.

Deuteronomy 32:43. The MT has four cola; the LXX has eight, including the phrase Hebrews 1:6 quotes ("let all the angels of God worship him"). 4Q44 (4QDeutᵍ), the Qumran Deuteronomy manuscript, preserves a Hebrew text close to the LXX's longer form, reading: הרנינו שמים עמו והשתחוו לו כל אלהים כי דם בניו יקום ונקם ישיב לצריו ולמשנאיו ישלם ויכפר אדמת עמו — "Rejoice, heavens, his people, and worship him, all gods; for he will avenge the blood of his children, return vengeance on his enemies, repay those who hate him, and atone for the land of his people." But the textual picture here is multi-witness in a way that prevents a tidy verdict. The Samaritan Pentateuch's Deuteronomy reads the short form, agreeing with the MT against 4Q44 and the LXX: הרנינו גוים עמו. So pre-Christ Hebrew witnesses split — 4Q44 and the Hebrew Vorlage of the LXX read the long form, while the proto-Masoretic tradition and the Samaritan tradition read the short. The apostle in Hebrews 1:6 follows the Hebrew form that the LXX preserved; the MT and SP follow the shorter Hebrew form. Both were pre-Christ Hebrew traditions.

Psalm 22:16. The MT reads כָּאֲרִי ("like a lion") — a phrase with no verb, awkward in context: "like a lion my hands and my feet." The LXX reads ὤρυξαν ("they dug / pierced"), implying a Hebrew Vorlage with כָּאֲרוּ (with waw, a verb form). Two independent pre-Christ Hebrew witnesses preserve the longer/verbal reading. The Nahal Hever Psalms scroll (5/6HevPs) reads:

[כי] [סבבוני] [כלבי]ם עדת מרעים הקיפוני כארו ידיה ורגלי

"[for] [dogs] [surround me], the assembly of evildoers encircle me; they pierced my hands and my feet" (5/6HevPs at Psa 22:16; brackets mark text reconstructed from context)

4Q88 (4QPsᶠ), a separate Qumran Psalms manuscript, attests the same verbal reading: ולשוני מדבש מל[קוחי] [ואל] עפר מות שופט — "and my tongue cleaves to my jaws; you have brought me to the dust of death" (the surrounding verses), with the piercing-verb form on the same line. Two pre-Christ witnesses; the verbal reading is not a single scroll's quirk.

One Hebrew letter (yod vs. waw) separates the two readings — a small visual difference that, in Hebrew transmission, is sometimes accidental and sometimes deliberate. The manuscript evidence alone cannot distinguish between (a) a scribe in the proto-Masoretic line mis-copying waw as yod at some point, (b) two parallel Hebrew Vorlages already in circulation pre-Christ with different consonants here, or (c) a deliberate alteration of the more pointed reading. What the manuscripts can show is the result: at a Christologically critical verse, two independent pre-Christ Hebrew manuscripts (5/6HevPs and 4Q88) read "they pierced," and the MT alone preserves "like a lion." The reader does not need to resolve the motive question to act on the textual one — the older Hebrew has the more pointed reading, and the older reading is the one to prefer.

A clearer case of theological alteration: Deuteronomy 32:8

The strongest single case for the MT being theologically altered from an older Hebrew reading does not sit in the eight commonly-cited variants. It sits in Deuteronomy 32:8.

The MT reads:

בְּהַנְחֵל עֶלְיוֹן גּוֹיִם בְּהַפְרִידוֹ בְּנֵי אָדָם יַצֵּב גְּבֻלֹת עַמִּים לְמִסְפַּר בְּנֵי יִשְׂרָאֵל

"When the Most High gave the nations their inheritance, when he separated the sons of man, he set the boundaries of the peoples according to the number of the sons of Israel" (Deu 32:8 MT)

The pre-Christ Hebrew at Qumran is preserved in 4Q37 (4QDeutʲ). The fragment reads:

בהנחי[ל] [עליון] [גוים] [בהפרידו] [בני] [אדם] [יצב] [גבלת] [עמים] [למספר] בני אלוהים

"...according to the number of the sons of God" (4Q37 at Deu 32:8; brackets mark text reconstructed from context, but the critical phrase בני אלוהים is physically preserved on the scroll)

4Q45 (4QDeutᵏ, paleo-Hebrew) preserves a partial parallel fragment that confirms the surrounding context, though the critical phrase falls in its lacuna. The LXX agrees with 4Q37: κατὰ ἀριθμὸν ἀγγέλων θεοῦ ("according to the number of the angels of God"). The replacement of "sons of God / Elohim" (בני אלוהים) with "sons of Israel" (בני ישראל) is not a yod/waw confusion or a scribal slip. It is a substantive lexical substitution — different words, different theology. The pre-Christ Hebrew Vorlage of the LXX and the Qumran manuscript 4Q37 both preserve the older "sons of God" reading; the proto-Masoretic tradition alone carries the substitution.

The motive is debated among scholars, but the alteration is not. The most widely accepted reading is that later rabbinic theology became uncomfortable with the divine-council picture — God allotting the nations to subordinate heavenly beings (cf. Psa 82) — and substituted "sons of Israel" to demythologize the verse. The change is not anti-Christian in its origin (the divine-council picture was problematic for various theological reasons inside Judaism), but it is unambiguously a theologically motivated alteration of the Hebrew text. The MT line here has been modified from the older Hebrew tradition.

Whether the motive at Deuteronomy 32:8 and the motive at Psalm 22:16 are the same, related, or unrelated cannot be settled from the manuscripts. What can be settled is the pattern: at some verses, the MT has been altered from older Hebrew readings, and the alterations are not purely scribal accidents. They reflect theological decisions made in the transmission line.

What the multi-witness picture means

Read together, these cases tell a more nuanced story than either "the MT is doctored" or "the MT was perfectly preserved." The Old Testament existed in multiple ancient Hebrew text-types before standardization. The proto-Masoretic tradition was stable and old, but it was not the only Hebrew text-type in circulation, and at a small number of specific verses the proto-MT tradition has carried readings that differ from older Hebrew witnesses in theologically pointed ways.

The LXX preserves another ancient Hebrew tradition that occasionally retained readings the proto-MT lost or altered. The Samaritan Pentateuch preserves a third Hebrew tradition that branched off pre-Christ and agrees with the MT against the LXX/DSS in some places and with the LXX/DSS against the MT in others. All four witnesses are real; none is the original. The honest position is to use them together, weighted by passage-specific evidence — and where the older canon preserves a reading the MT lacks, follow the older reading.

The doctoring charge in its wholesale form — that the entire MT was rewritten after Christ to obscure messianic passages — is refuted decisively by the manuscript evidence. 1QIsaᵃ at ~95% identity with MT Isaiah, the Samaritan Pentateuch's broad agreement with the MT for the Torah, and the MT's preservation of plainly Christologically charged readings (Zec 12:10's "pierced," Isa 7:14's עלמה, the Servant Songs intact) all argue against a systematic anti-Christian editing program.

But the doctoring charge in a narrower form — that the proto-MT tradition has, at specific verses, carried readings that differ from older Hebrew witnesses in theologically motivated ways — is not refuted. Deuteronomy 32:8 demonstrates it; Psalm 22:16 plausibly demonstrates it. Whether the motive at any specific verse was anti-Christian or pre-Christian (anti-divine-council, anti-anthropomorphism, anti-polytheism, etc.) typically cannot be settled. The practical implication is the same either way: at these specific verses, the older Hebrew should be preferred. The text is what it is.

VII. The Wider Canon Question — Hebrews 1:3, Wisdom of Solomon, and 1 Enoch

There is a consequence to "use the LXX" wholesale that the popular form of the claim does not name: choosing the LXX wholesale means choosing a wider canon.

The MT corresponds to the 39 books of the Hebrew Bible — the canon Jewish communities transmitted, debated, and finally fixed in the centuries around the turn of the era. The LXX, as historically received and transmitted in the great Greek codices (Sinaiticus, Vaticanus, Alexandrinus), includes additional books: Tobit, Judith, Wisdom of Solomon, Sirach, 1–2 Maccabees (and in some manuscripts 3–4 Maccabees), Baruch, the Letter of Jeremiah, the Greek additions to Daniel (Prayer of Azariah, Song of the Three Young Men, Susanna, Bel and the Dragon), 1 Esdras, the Odes, the Psalms of Solomon. Roman Catholicism formally accepted these as canonical at the Council of Trent (AD 1546). Eastern Orthodoxy accepts a still wider list. Protestantism follows the Hebrew canon and treats these as Apocrypha — historically valuable but not doctrinally binding.

"Use the LXX" wholesale is therefore not only a textual preference. It is an implicit canon decision. Most forms of the wholesale claim do not address that consequence.

The harder lexical question is what to make of cases where canonical NT vocabulary is shared with deuterocanonical Greek. The clearest case sits at the opening of Hebrews. The author writes:

ὃς ὢν ἀπαύγασμα τῆς δόξης καὶ χαρακτὴρ τῆς ὑποστάσεως αὐτοῦ

"who being the radiance (ἀπαύγασμα) of the glory and the exact expression of his substance" (Heb 1:3)

The word ἀπαύγασμα (G541) — "radiance, off-flash, effulgence" — occurs exactly twice across the canonical and deuterocanonical Greek corpus. Once in canonical Scripture (Heb 1:3), describing the Son. Once in the deuterocanonical Wisdom of Solomon, describing personified Wisdom: ἀπαύγασμα γάρ ἐστιν φωτὸς ἀϊδίου ("she is the radiance of eternal light", LXX Wis 7:26). The author of Hebrews has reached for Wisdom of Solomon's exact vocabulary to describe Christ.

The principle this requires is plain. The author of Hebrews is immersed in Greek Jewish wisdom vocabulary. He reaches for Wisdom of Solomon's language because it provides the conceptual furniture he needs — light, glory, image, power — to describe the eternal relation of the Son to the Father. The lexical borrowing is real and dense: four shared theological terms across the same verse-cluster. But this borrowing does not canonize Wisdom of Solomon. The same kind of borrowing happens elsewhere in the New Testament with non-Jewish sources. Paul borrows from the pagan poet Aratus at Acts 17:28 (τοῦ γὰρ καὶ γένος ἐσμέν — "for we are also his offspring"). The principle holds: NT authors freely used the linguistic and conceptual furniture of their Greek-speaking world.

Jude pushes the question further. He cites 1 Enoch directly:

προεφήτευσεν δὲ καὶ τούτοις ἕβδομος ἀπὸ Ἀδὰμ Ἑνὼχ λέγων· ἰδοὺ ἦλθεν κύριος ἐν ἁγίαις μυριάσιν αὐτοῦ

"and Enoch, the seventh from Adam, prophesied also to these, saying: behold, the Lord came with myriads of his holy ones" (Jud 1:14, citing 1En.1.9)

1 Enoch is pseudepigraphal — lower in historical-witness weight than even the deuterocanonical works. Jude's citation establishes 1 Enoch's historical and linguistic value. It does not establish 1 Enoch's canonical authority. Almost no Christian tradition, ancient or modern, treats 1 Enoch as canonical (the Ethiopian Orthodox canon is the rare exception). The principle holds again: NT use of a text does not canonize that text. It establishes that the NT author knew the text and found in it language that served the Spirit-led argument.

The textually honest position is to use the LXX as a translation witness alongside the MT, retain the Hebrew canon as the primary doctrinal authority, and read the deuterocanonical and pseudepigraphal works for historical and linguistic context — exactly as the NT authors themselves engaged with the wider Jewish literature of their day. "Use the LXX wholesale" smuggles in a canon expansion the apostles' own practice does not require.

VIII. Where the LXX Is Also Weaker Than the MT

Textual honesty cuts both ways. Where the LXX preserves an older or fuller reading — Isaiah 53:11, Deuteronomy 32:43 — the previous sections have said so plainly. Where the LXX has weakened or paraphrased the Hebrew, the same honesty requires the same plainness.

Three cases.

Genesis 3:15 — the protevangelium. The Hebrew of the seed-promise reads:

הוּא יְשׁוּפְךָ רֹאשׁ וְאַתָּה תְּשׁוּפֶנּוּ עָקֵב

hûʾ yĕšûfĕkā rōʾš wĕʾattāh tĕšûfennû ʿāqēb

"he will bruise / crush your head, and you will bruise / crush his heel" (Gen 3:15)

The verb is H7779 שׁוּף (šûf), an aggressive verb meaning "to bruise, strike, snap at." It is a verb of violence. The LXX renders the same line:

αὐτός σου τηρήσει κεφαλήν, καὶ σὺ τηρήσεις αὐτοῦ πτέρναν

"he will watch / guard your head, and you will watch / guard his heel"

The LXX verb is G5083 τηρέω — "to watch over, guard, keep." The verb has shifted from violent crushing to protective vigilance. The Hebrew Vorlage almost certainly had the same שׁוּף, because the Samaritan Pentateuch — an independent pre-Christ Hebrew tradition of the Torah — preserves the same violent verb that the MT carries: ו איבה אשׁית בינך... הוא ישׁופך ראשׁ ו אתה תשׁופנו עקב. Two pre-Christ Hebrew witnesses (MT-Vorlage + SP) attest the crushing verb; the LXX has made an interpretive substitution that softens the central image of the seed conflict. (Some later Greek translation traditions — Aquila and Symmachus — restore a more aggressive verb here, but the Old Greek form, and the form most widely circulated in the early church, is τηρέω in both clauses.) The MT preserves the harder, more violent reading, the SP confirms it, and the harder reading — in textual criticism — is generally more likely to be original (a translator is far more likely to soften violence than to invent it). At Genesis 3:15, the MT reads what Moses wrote, and the Samaritan Pentateuch agrees.

Proverbs 8:22 — Wisdom's origin. The Hebrew reads:

יְהוָה קָנָנִי רֵאשִׁית דַּרְכּוֹ

YHWH qānānî rēʾšît darkô

"The LORD acquired / possessed me at the beginning of his way" (Pro 8:22)

The verb is H7069 קָנָה (qānāh). Its semantic range covers "acquire, possess, get" and (in poetic contexts) "produce, beget, create." The Hebrew is genuinely ambiguous between these senses; both are attested. The LXX renders it:

κύριος ἔκτισέν με ἀρχὴν ὁδῶν αὐτοῦ

"The LORD created me as the beginning of his ways"

The verb is G2936 κτίζω — "to found, to create from nothing." The LXX has resolved the Hebrew ambiguity in the direction of unambiguous creation language. This LXX choice was used extensively in the fourth-century Arian controversy. Arius cited LXX Pro 8:22 to argue that Wisdom — and therefore, on his identification of Wisdom with the pre-incarnate Son, the Son himself — was a created being. The MT's "acquired / possessed" does not as easily support that reading. The LXX's interpretive move had downstream theological consequences the MT's deliberately ambiguous Hebrew avoided.

Zechariah 12:10. Already worked through in §III. The LXX's κατωρχήσαντο ("they mocked") replaces דָּקַר ("they pierced"), losing the central Christological image — against the LXX's own standard equivalence in every other H1856 occurrence. This is the single strongest case of LXX inferiority to the MT in the entire study.

The conclusion of this section is direct. The LXX is a translation. Translations are interpretive. Some LXX choices preserve older Hebrew the MT lost; some LXX choices reinterpret the Hebrew in ways the MT does not. The popular form of the "use the LXX" claim presents only the first category as evidence; textual honesty requires presenting both. A reader who wants the unmediated Hebrew of Genesis 3:15 — the crushed-head verb — must read the MT, because the LXX softened it. A reader who wants the original Christological image at Zechariah 12:10 — the pierced one — must read the MT, or read with John, because the LXX lost it.

The LXX is not the Hebrew Bible. It is the Greek Hebrew Bible — a separate witness, ancient and valuable, but with its own translational character. Treating it as transparent to the Hebrew is a category error.

IX. Conclusion — The Honest Verdict

Three findings, restated plainly against the question that opened the study: has the Hebrew Bible we have today been doctored since the coming of Christ?

Finding one: the MT as a whole is not a Christian-era rewrite. The Great Isaiah Scroll (1QIsaᵃ, c. 150–100 BC) predates the resurrection by up to two centuries, and predates the Aleppo and Leningrad Codices by roughly a thousand years. It is approximately 95% identical to the Masoretic Isaiah. The Samaritan Pentateuch — an independent Hebrew tradition that split from mainstream Judaism before Christ — agrees broadly with the MT across the Torah. Two independent pre-Christ Hebrew witnesses converge on substantially what the Masoretes set down at AD 900. That fact refutes the wholesale doctoring charge: the MT was not produced after Christ to obscure messianic passages. The Masoretes preserved a Hebrew text that was already substantially stable before Christ was born.

Finding two: specific verses are altered from older Hebrew readings, and at least one is theologically motivated. Deuteronomy 32:8 is the clearest case. The Qumran Deuteronomy manuscript 4Q37 (4QDeutʲ) reads "the sons of God / Elohim" (בני אלוהים); the MT reads "the sons of Israel" (בני ישראל). This is not a scribal slip — it is a substantive word replacement, and the most plausible explanation is theological discomfort in later Judaism with the divine-council picture. The motive at Deuteronomy 32:8 is most likely not anti-Christian but anti-mythological — and that does not make the alteration less real. Psalm 22:16's "like a lion" (MT) vs. "they pierced" (5/6HevPs and 4Q88) is a separate case where the mechanism (yod/waw confusion vs. deliberate alteration) cannot be settled from the manuscripts, but the result is the same: two independent pre-Christ Hebrew witnesses (the Nahal Hever Psalms scroll and 4QPsᶠ) both read "they pierced," and the MT does not. Whether the change at Psalm 22:16 was deliberate or accidental, the older reading is the one to prefer.

Finding three: the apostles read the Hebrew the MT preserves at Zechariah 12:10 — and so did the pre-Christ Hebrew at Qumran. The Hebrew verb H1856 דָּקַר ("to pierce") is rendered G1574 ἐκκεντέω in every traceable LXX occurrence except LXX Zec 12:10, which anomalously substitutes κατωρχήσαντο ("mocked"). John 19:37 and Revelation 1:7 both restore G1574 ἐκκεντέω — the standard Greek equivalent of דָּקַר that the LXX Zechariah translator broke. The pre-Christ Hebrew at this verse is preserved in 4Q80 (4QXIIᵉ), the Qumran Twelve Prophets manuscript, reading דקרו — the same root the MT preserves at AD 900. Three witnesses across a millennium of transmission (4Q80 at Qumran in the late Second Temple period, apostolic Greek in the first century AD, Masoretic Hebrew at AD 900) converge on the same Hebrew reading. The most Christologically charged single verb in the prophets was preserved, not altered.

The textually honest verdict is this:

The MT is a carefully preserved Hebrew tradition, broadly faithful to the proto-MT Hebrew that was already in circulation before Christ. It is not a wholesale rewrite. But at a small number of specific verses, the proto-MT tradition has carried readings that differ from older Hebrew witnesses in theologically pointed ways. Some of these differences are accidents of transmission; at least one (Deu 32:8) is most plausibly a deliberate theological alteration. Where the older Hebrew preserves a reading the MT lost or altered, the older reading should be preferred — not because of conspiracy, but because of textual age and witness agreement. The motive question is sometimes answerable and sometimes not; the practical guidance is the same either way.

The apostles read this multi-witness Hebrew Bible. They quoted both the LXX and the proto-MT Hebrew, choosing the text-form that served the argument. They did not commit themselves to a single text-tradition wholesale, and neither should we. The companion study Cut Without Hands works the parallel question one level deeper for the book of Daniel — where the New Testament's Greek Daniel is not the LXX Old Greek (LXX-OG) but Theodotion's later, more literal translation, almost universally. Same principle, different precision question: the apostles read carefully, chose the form that served the argument, and did not commit themselves to a single text-tradition wholesale.

The Bible the apostles quoted was multi-source by design. A reader who wants their Bible should be the same. The wholesale claim that the MT was rewritten after Christ is empirically false — refuted by 1QIsaᵃ, the Samaritan Pentateuch, and the MT's preservation of plainly Christologically charged readings (Zec 12:10's "pierced," Isa 7:14's עלמה, the Servant Songs intact). But the converse claim — that the MT is everywhere identical to the pre-Christ Hebrew — is also empirically false, refuted by Deuteronomy 32:8 most clearly and by Psalm 22:16 plausibly. The truth sits in the middle: the MT is mostly preserved, partially altered, and where the older canon preserves a different reading, the older canon wins on textual grounds alone. No conspiracy is required to reach that conclusion, and no conspiracy is sufficient to undermine it.
