Who Hardened Pharaoh's Heart

The question has divided readers for as long as the chapter has been read: who hardened Pharaoh's heart? If God did it, how is Pharaoh blamed? If Pharaoh did it, what does the text mean when YHWH says he will do it himself? The argument is usually conducted at the level of theology, with proof-texts traded across a table. But the Hebrew narrative does not argue the question. It stages it — verse by verse, verb by verb — and the staging is more careful than either camp tends to admit. Exodus 7 is where the staging begins in earnest, and where the chapter's own grammar tells us how to read the whole plague cycle.

I. The chapter's frame (Exodus 7:1-7)

The chapter opens by redefining the contest. YHWH tells Moses: רְאֵה נְתַתִּיךָ אֱלֹהִים לְפַרְעֹה (reʾeh netatticha ʾelohim le-farʿoh), "See, I have made you as elohim to Pharaoh," and Aaron נְבִיאֶךָ (neviʾecha, from H5030, "prophet"), "your prophet" (Exodus 7:1). The Egyptian king who claims divine status is to be confronted by a man set over him as a god, with Aaron as the mouthpiece. The oldest Hebrew witnesses preserve this verse without substantive variant — Qumran fragments carry the Masoretic reading.

Then comes the second of two pre-plague forecasts of the hardening. The first stood back in the commissioning at the bush, where God said וַאֲנִי אֲחַזֵּק אֶת־לִבּוֹ (va-ʾani ʾachazzeq ʾet-libbo), "but I will make his heart firm" (Exodus 4:21) — a Piel of חָזַק (chazaq, H2388), with God in the first person as the explicit agent. The second forecast comes here: וַאֲנִי אַקְשֶׁה אֶת־לֵב פַּרְעֹה (va-ʾani ʾaqsheh ʾet-lev parʿoh), "and I will harden Pharaoh's heart" (Exodus 7:3), a Hiphil of קָשָׁה (qashah, H7185). What matters is the order of operations. Before Pharaoh has refused even once in the plague narrative, God has twice declared, in the first person, that he will harden. The hardening is not a divine reaction to Egyptian stubbornness; it is announced as strategy.

And the strategy has a stated purpose. The forecast at 7:3 runs straight into a purpose clause: וְהִרְבֵּיתִי אֶת־אֹתֹתַי וְאֶת־מוֹפְתַי (ve-hirbeti ʾet-ʾototai ve-ʾet-mofetai), "and I will multiply my signs and my wonders in the land of Egypt" (Exodus 7:3). The hardening exists to multiply the signs. A Pharaoh who released Israel at the first demand would generate one sign; a Pharaoh whose resistance is sustained generates ten. The end is named two verses on: וְיָדְעוּ מִצְרַיִם כִּי־אֲנִי יְהוָה (ve-yadʿu mitzrayim ki-ʾani YHWH), "and the Egyptians shall know that I am YHWH" (Exodus 7:5). The hardening serves the recognition. Pharaoh had thrown down the gauntlet in chapter 5 — לֹא יָדַעְתִּי אֶת־יְהוָה (loʾ yadaʿti ʾet-YHWH), "I do not know YHWH" (Exodus 5:2) — and the whole machinery of the plagues is built to answer that ignorance, in him and in his nation.

The frame is sealed by repetition. The opening announcement of 7:1-7 returns almost verbatim at the close of the plague cycle, where the narrator declares that Moses and Aaron did all these wonders and YHWH hardened Pharaoh's heart (Exodus 11:9-10). What is forecast at the start is reported fulfilled at the end. Between those two posts the narrative will lay out the hardening with a precision the popular summary flattens.

II. The crux: who hardened the heart?

The dispute can be settled only by reading every hardening in order and noting two things at each: the verb's stem (its binyan), and the grammatical subject. The distinction is not pedantic. In Hebrew the Qal stem of a verb like חָזַק is intransitive — "to become firm," with the heart itself as the subject and no agent named. The Piel and Hiphil stems are causative — "to make firm," with an explicit agent who acts upon the heart. To say "his heart became hard" (Qal) is a different grammatical claim from "he made his heart hard" (Hiphil) or "YHWH made his heart hard" (Piel). The English word "hardened" erases all three into one. The table below restores them.

Read the table top to bottom and the staging is unmistakable. The two forecasts come first (4:21; 7:3), both in the first person, God as agent. Then through the first five plagues — to the end of the livestock plague at 9:7 — every hardening is one of two kinds. It is either a Qal intransitive, where the heart itself is the subject and no agent is named (7:13, 7:22, 8:19, 9:7), or a Hiphil with Pharaoh as the explicit subject (8:15, 8:32). Not once in those five plagues is YHWH the grammatical subject of the verb.

Then the hinge. At the sixth plague, the boils, the narrator writes for the first time: וַיְחַזֵּק יְהוָה אֶת־לֵב פַּרְעֹה (va-yechazzeq YHWH ʾet-lev parʿoh), "and YHWH made firm the heart of Pharaoh" (Exodus 9:12). This is a Piel of חָזַק, and YHWH is the explicit subject. It is the first verse in the whole narrative where God is grammatically the one who hardens. The witnesses are unanimous here — Qumran fragments, the consolidated Dead Sea Scroll Hebrew, and the Greek (which reads "the Lord hardened") all agree. From this point forward, through plagues eight, nine, and ten, and into the pursuit at the sea, YHWH is the consistent explicit agent (10:20, 10:27, 11:10, 14:8). The trajectory peaks at 14:17 with a Piel active participle, מְחַזֵּק (mechazzeq), "I am hardening" — the most intensive form of all, God as the present, ongoing agent at the moment Egypt enters the sea.

This is what the grammar shows, and it must be reported as it stands. The text holds two things together without collapsing either. On one side, divine sovereignty is unmistakable: God forecasts the hardening twice before a single plague (4:21; 7:3), he becomes the explicit agent from the sixth plague on (9:12), and at 10:1 he reaches back and claims the whole sequence — הִכְבַּדְתִּי אֶת־לִבּוֹ (hikbadti ʾet-libbo), "I have made his heart heavy" — covering even the earlier self-hardenings within his stated purpose. On the other side, human responsibility is equally unmistakable: in the early plagues Pharaoh is named, in the Hiphil, as the one who makes his own heart heavy (8:15, 8:32), and even after God has taken up the role, Pharaoh-hardening recurs (9:34), and the retrospective Passover speech still says הִקְשָׁה פַרְעֹה (hiqshah farʿoh), "Pharaoh made his heart stubborn" (Exodus 13:15). The narrative does not assign the early plagues to Pharaoh and the late ones to God as if the responsibility shifted hands. It frames the whole — Pharaoh's self-hardening and God's hardening alike — inside the forecast that opened the contest. Pharaoh hardens himself, and God hardens Pharaoh, and the text declares the second from the first verse without ever excusing the first.

A note on what the hardening targets. The organ is לֵב (lev, H3820, "heart"), which occurs of Pharaoh repeatedly across these chapters. In Hebrew the lev is not the seat of emotion but the seat of will, decision, and understanding — the faculty of moral discernment. To harden the lev is not to make a man sad or angry but to render his decision-making unresponsive. Whatever the agent, the thing acted upon is the will itself.

III. The three verbs

The table uses three different Hebrew roots, and they are not interchangeable. Each carries a distinct metaphor for what happens to a heart that will not yield.

The dominant verb is חָזַק (chazaq, H2388), which carries fifteen hardening-relevant uses across Exodus. Its root sense is not stubbornness as indecision but grip — to seize, to hold fast, to be strong. A chazaq heart is a clenched fist that will not open. The second is כָּבֵד (kaved, H3513), ten uses, whose sense is weight and dullness — a heart grown so heavy it cannot respond, an organ deadened past feeling. The third is קָשָׁה (qashah, H7185), two uses (7:3; 13:15), the language of stiff, unyielding material that will not bend. The same root gives the standing biblical phrase קְשֵׁה־עֹרֶף (qesheh-ʿoref), "stiff-necked" — and the irony lands later, when Israel does to its own neck what Pharaoh did to his heart, in the eleven occurrences of that construction from Deuteronomy 10:16 onward. At Deuteronomy 2:30 the very verb and stem of the Pharaoh forecast reappears: YHWH הִקְשָׁה (hiqshah) the spirit of Sihon of Heshbon, with a purpose clause matching Exodus — "that I might give him into your hand." Five pre-Christ witnesses confirm that reading. Pharaoh is not the only king God hardens for judgment. And the wisdom tradition draws the principle to its point with the same verb: מִי־הִקְשָׁה אֵלָיו וַיִּשְׁלָם (mi-hiqshah ʾelav va-yishlam), "Who has hardened himself against him and prospered?" (Job 9:4) — resistance to God, Pharaoh's or anyone's, is a losing wager.

The deepest of the three is kaved, because its root is the hinge of the whole book. H3513 (kaved, "to be heavy, dull") and H3519 (kavod, "glory, honor, weight") are one and the same root; glory in Hebrew is, at bottom, weight. So Pharaoh makes his heart heavy (kaved) against God — and God announces, in the same root, that he will make himself weighty, will gain glory, over Pharaoh. At the sea God says אִכָּבְדָה בְּפַרְעֹה (ʾikkavedah be-farʿoh), "I will gain glory over Pharaoh" (Exodus 14:4), and repeats it at 14:17 — both times the Niphal of the same root H3513 that names Pharaoh's self-dulling. The man who weighs his own heart down with refusal becomes the stage on which God's own weight is displayed. The hardening and the glory are spelled with the same consonants.

This vocabulary did not stay in Egypt. Generations later the Philistine priests, debating whether to return the captured ark, warned their lords: לָמָּה תְכַבְּדוּ אֶת־לְבַבְכֶם כַּאֲשֶׁר כִּבְּדוּ מִצְרַיִם וּפַרְעֹה אֶת־לִבָּם (lammah techabbedu ʾet-levavchem ka-ʾasher kibbedu mitzrayim u-farʿoh ʾet-libbam), "Why should you harden your hearts as Egypt and Pharaoh hardened their hearts?" (1 Samuel 6:6). The verb is kaved, Pharaoh's own verb. This is the earliest backward citation of the Exodus hardening inside the canon — pagan priests treating the plague cycle as a settled cautionary tale long before any theologian framed it as a doctrine. The Dead Sea Scroll Hebrew and a Qumran witness preserve the verse.

IV. The staff, the dragon, the magicians (Exodus 7:8-13)

Before the first plague, there is a sign in the throne room, and it is more than a trick. At the bush, Moses' staff had become a נָחָשׁ (nachash, H5175), an ordinary snake — the common Hebrew word, the creature Moses fled from (Exodus 4:3). But when Aaron throws down the staff before Pharaoh, the text changes the word. It becomes a תַּנִּין (tannin, H8577): וַיְהִי לְתַנִּין (va-yehi le-tannin), "and it became a tannin" (Exodus 7:10). The word occurs three times, all packed into 7:9-12, and the Greek renders it δράκων (drakōn), "dragon." English translations flatten both words to "serpent" and lose the escalation entirely.

The tannin is not a generic reptile. It is the chaos-creature of the Hebrew imagination — the great sea-monster of the fifth day of creation (Genesis 1:21), the dragon YHWH slays in the sea (Isaiah 27:1), the heads YHWH crushes in the waters (Psalm 74:13). And it is precisely the title Ezekiel later hangs on Pharaoh himself: הַתַּנִּים הַגָּדוֹל הָרֹבֵץ בְּתוֹךְ יְאֹרָיו (ha-tannim ha-gadol ha-rovetz be-tokh yeʾorav), "the great tannin lying in the midst of his Nile streams" (Ezekiel 29:3). When Aaron's staff becomes a tannin in Pharaoh's court, it is dragon set against dragon. The magicians answer in kind — their staffs become tannin too — and then וַיִּבְלַע מַטֵּה־אַהֲרֹן אֶת־מַטֹּתָם (va-yivlaʿ matteh-ʾaharon ʾet-mattotam), "Aaron's staff swallowed their staffs" (Exodus 7:12). The verb is בָּלַע (bala, H1104), to swallow, devour. It is the same verb that closes the whole confrontation at the sea: וַתִּבְלָעֵמוֹ הָאָרֶץ (va-tivlaʿemo ha-ʾaretz), "the earth swallowed them" (Exodus 15:12). The first sign and the final judgment use one verb; the staff swallowing the staffs is the sea swallowing the army in miniature, staged before the plagues begin. The dragon-thread runs to the end of the canon: the great dragon cast down is "that ancient serpent, who is called the devil and Satan" (ὁ δράκων ... ὁ ὄφις ὁ ἀρχαῖος, Revelation 12:9; 20:2) — the Pharaoh-dragon of the Nile opened out into the last anti-God power.

The men holding those staffs are the חַרְטֻמִּים (chartummim, H2748), the Egyptian magicians — a word that appears eleven times across ten verses in the canon, all in Genesis, Exodus, and Daniel. The distribution is itself a pattern. They first appear summoned to Pharaoh's court to read his dreams, where they fail and Joseph succeeds because "the spirit of God" is in him (Genesis 41:8, 41:24, 41:38). They appear here, against Moses, where they replicate the tannin sign and the first two plagues but cannot make gnats and confess, אֶצְבַּע אֱלֹהִים הִוא (ʾetzbaʿ ʾelohim hiwʾ), "this is the finger of God" (Exodus 8:19); by the sixth plague they cannot even stand, struck with boils themselves (Exodus 9:11), and they vanish from the story. The same caste reappears in Babylon's court, where Daniel and his friends are found "ten times better" than all the chartummim (Daniel 1:20; 2:2 — the same Hebrew word; Daniel's later Aramaic chapters use the cognate term, but the title and the role are unchanged). Across all three courts the magicians are the foil: the professional wisdom of empire, summoned and found empty against the servant in whom God's Spirit works. Paul reads them exactly this way, naming two of the Exodus magicians, Jannes and Jambres, as a type of those who "oppose the truth" in the last days (2 Timothy 3:8) — a tradition of their names that the Old Testament itself never records. And the magicians' own forced confession — "this is the finger of God" — becomes, on Jesus' lips, the sign of the kingdom: "if it is by the finger of God (ἐν δακτύλῳ θεοῦ) that I cast out demons, then the kingdom of God has come upon you" (Luke 11:20).

V. Romans 9 and the two NT hardening streams

Paul reaches back to this chapter to make one of the hardest claims in his letters. In Romans 9 he quotes Exodus directly — γὰρ ἡ γραφὴ τῷ Φαραὼ ὅτι εἰς αὐτὸ τοῦτο ἐξήγειρά σε ὅπως ἐνδείξωμαι ἐν σοὶ τὴν δύναμίν μου (hē graphē tō Pharaō…), "the Scripture says to Pharaoh, 'For this very purpose I raised you up, that I might show my power in you, and that my name might be proclaimed in all the earth'" (Romans 9:17), citing Exodus 9:16 — the very verse, in the boils sequence, that frames the hardening as a display of the name. Then Paul draws the conclusion: ὃν δὲ θέλει σκληρύνει (hon de thelei sklērynei), "and he hardens whom he wills" (Romans 9:18).

The verb Paul chooses at 9:18 is σκληρύνω (sklērynō, G4645), and it is not arbitrary. It is the verb the Greek Old Testament uses for the Exodus hardening — at the forecast (the Septuagint of Exodus 7:3, future active, God speaking) and at the first divine hardening (the Septuagint of Exodus 9:12, aorist active, "the Lord hardened") — 9:12 being the immediate neighbor of the verse Paul quotes for God's name (Exodus 9:16). Paul is reading the Greek text, and that text already leans more decisively toward divine agency than the Hebrew does. Where the Hebrew of 7:22 has a Qal intransitive with no agent — "the heart became firm" — the Greek renders it ἐσκληρύνθη (esklērynthē), an aorist passive that implies an unstated agent. The careful three-way Hebrew structure (God, Pharaoh, no-agent) is partly absorbed into the passive in Greek. When Paul concludes "he hardens whom he wills," he is generalizing a principle the Greek Exodus had already framed.

But Paul does not let the Exodus type swallow everything, and here the translations betray a distinction the Greek keeps sharp. There is a second hardening tradition in Scripture, and it uses a different verb. The Isaiah 6 commission — "make the heart of this people fat" (Isaiah 6:10) — is taken up in the Gospels and in Paul with πωρόω (pōroō, G4456), a verb drawn from the medical image of a callus, a thickening of tissue past feeling. It is πωρόω, not σκληρύνω, that John uses when he says God "hardened their heart" so they could not believe (John 12:40), and it is πωρόω that Paul uses for Israel in Romans 11:7 — οἱ δὲ λοιποὶ ἐπωρώθησαν (hoi de loipoi epōrōthēsan), "the rest were hardened." The same verb describes the disciples' own dullness after the loaves (Mark 6:52; 8:17) and the veiled minds of those reading the old covenant (2 Corinthians 3:14). Paul, in one sweep of argument across Romans 9 to 11, uses both: σκληρύnω for the foreign king hardened as in the Exodus (9:18), and πωρόω for elect-but-unbelieving Israel (11:7). The theological function is the same — a heart rendered unresponsive to revelation — but the provenance and vocabulary are distinct, and to flatten them into one English word "harden" is to lose half of what Paul is doing. The Pharaoh-stream and the Israel-stream are not the same stream.

And the Exodus verb is finally turned on the covenant community itself. Quoting the Ninety-fifth Psalm, Hebrews presses the warning: σήμερον ἐὰν τῆς φωνῆς αὐτοῦ ἀκούσητε, μὴ σκληρύνητε τὰς καρδίας ὑμῶν (sēmeron ean tēs phōnēs autou akousēte, mē sklērynēte tas kardias hymōn), "Today, if you hear his voice, do not harden your hearts" (Hebrews 3:7-8, repeated at 3:15 and 4:7). The σκληρύνω that fell on Pharaoh becomes a summons to everyone who hears the gospel: the hardened heart is not only a tyrant's danger but the worshiper's, and the wilderness generation that heard God's voice and hardened anyway is held up as the warning.

VI. The first plague: Nile to blood (Exodus 7:14-25)

The first plague proper opens with God's own diagnosis of the heart, and it uses the kaved root again: כָּבֵד לֵב פַּרְעֹה (kaved lev parʿoh), "Pharaoh's heart is heavy" (Exodus 7:14) — a stative, the settled condition before the strike. Then the strike: Aaron lifts the staff, and the Nile turns to דָּם (dam, H1818), "blood" — a word that runs twenty-nine times across the book, and that was rehearsed long before in the private third sign at the bush, where water poured on dry ground became blood (Exodus 4:9). The private sign was the template; the public plague is its enactment on the great river itself, the יְאֹר (yeʾor, H2975), the Nile that Egypt deified and depended on.

The target of the plague is not the river but the recognition. The whole sequence is bracketed by the recognition formula — the pairing of יָדַע (yadaʿ, H3045, "know") with the divine name, which co-occurs twenty-eight times across Exodus. It is spoken twice in this chapter, and the grammar of each is precise. To the nation, plural: וְיָדְעוּ מִצְרַיִם כִּי־אֲנִי יְהוָה (ve-yadʿu mitzrayim), "the Egyptians shall know that I am YHWH" (Exodus 7:5). To Pharaoh, singular: בְּזֹאת תֵּדַע כִּי אֲנִי יְהוָה (be-zoʾt tedaʿ ki ʾani YHWH), "by this you shall know that I am YHWH" (Exodus 7:17). Both answer the king's opening boast — "I do not know YHWH" (Exodus 5:2). The plagues are not punishment for its own sake; they are an education in the name, forced upon a man who denied it. This is the formula Ezekiel will inherit and repeat dozens of times over his own judgment oracles, the same prophet who names Pharaoh the tannin of the Nile.

And the king will not learn. The magicians replicate even this — they too turn water to blood by their secret arts (Exodus 7:22) — and so Pharaoh's heart becomes firm again, the Qal intransitive of 7:22, and the narrator's verdict is devastating in its understatement: וְלֹא־שָׁת לִבּוֹ גַּם־לָזֹאת (ve-loʾ-shat libbo gam-la-zoʾt), "he did not set his heart even to this" (Exodus 7:23). The plague reaches forward, too. The water-to-blood judgment becomes the language of the last things: the two witnesses of Revelation are given "power over the waters to turn them into blood, and to strike the earth with every plague" (Revelation 11:6) — Moses-and-Aaron typed, in Exodus vocabulary, αἷμα (haima, "blood") and πληγή (plēgē, "plague"). The bowls of wrath echo it again, the sea and rivers becoming blood (Revelation 16:3-4). The Nile turned to blood is the first note of a judgment that the canon carries to its final pages.

VII. The Second Temple horizon and the theology

The hardening troubled readers long before Paul. The Greek-speaking Jewish wisdom of the Second Temple period wrestled with it from two directions — and these texts, valuable as historical witnesses to how Jews before the New Testament read the plagues, carry weight as background, not as Scripture. The book of Wisdom reads the plagues as exact retribution: δι᾽ ὧν τις ἁμαρτάνει, διὰ τούτων κολάζεται (di hōn tis hamartanei…), "by what things a man sins, by these he is punished" (Wisdom 11:16, deuterocanonical) — Egypt drowned the Hebrew infants in the Nile, so the Nile is struck first. From the other direction, Ben Sira insists on the freedom of the will against any reading that makes God the author of sin: αὐτὸς ἐξ ἀρχῆς ἐποίησεν ἄνθρωπον καὶ ἀφῆκεν αὐτὸν ἐν χειρὶ διαβουλίου αὐτοῦ (…en cheiri diabouliou autou), God "left him in the hand of his own counsel" (Sirach 15:14, deuterocanonical). The two impulses — God's exact justice and the integrity of human choice — are the same two the Hebrew narrative had already held in tension.

That tension is the point, and the grammar will not let us dissolve it in either direction. The plain reading is not a compromise between two camps; it is what the verbs say, read in order. God forecasts the hardening before Pharaoh has refused once (Exodus 4:21; 7:3). Through five plagues Pharaoh hardens himself, named in the Hiphil as the agent (Exodus 8:15, 8:32), or his heart simply becomes firm with no agent named (Exodus 7:13, 7:22, 8:19, 9:7). From the sixth plague God becomes the explicit subject (Exodus 9:12), and from the eighth he does not relent. Yet even then Pharaoh's own hardening recurs (Exodus 9:34), and the retrospective Passover speech still lays the refusal at Pharaoh's feet (Exodus 13:15). The man who weighs his heart down (kaved) becomes the platform for the weight of God's glory (kavod, Exodus 14:4, 17). Pharaoh is fully responsible, and God is fully sovereign, and the text declares the second from its opening verse without ever excusing the first. The question "who hardened Pharaoh's heart?" has, in the end, a single honest answer the chapter supplies: both — and God said so first.
