When I See the Blood

One sentence holds this chapter together, and it is the sentence the whole feast is named for: וְרָאִיתִי אֶת־הַדָּם וּפָסַחְתִּי עֲלֵכֶם — "and when I see the blood, I will pass over you" (Exo 12:13). This is narrative-embedded law: YHWH speaks the ordinance to Moses and Aaron בְּאֶרֶץ מִצְרַיִם, "in the land of Egypt" (Exo 12:1) — the one piece of legislation given on Egyptian soil, the night before the tenth plague falls. Part 11 read the verdict aloud, the sentence pronounced over Egypt; here the people are handed the one thing that will make the distinction hold on their own doorposts: blood. Two motions run through the night and the chapter holds them in tension. A destroyer will pass through Egypt; YHWH will pass over Israel. The second verb (פָּסַח, H6452) is the one the feast carries as its name, and it is the one most often misread — as if it meant merely to skip the house. The text will say otherwise. And note where the blood goes: on the doorposts and lintel, on the outside of the house, where the family inside cannot see it. The sign is not Israel's badge to display. It is for God to read.

The Calendar Reset

The ordinance opens with a recipient and a date. YHWH speaks אֶל־מֹשֶׁה וְאֶל־אַהֲרֹן — "to Moses and Aaron" (Exo 12:1); the priestly co-recipient is no accident, for this is the law that founds a cult. It is the only legislation delivered in Egypt — on Egyptian soil, before the people ever leave (other pre-Sinai statutes come later, on the way: the firstborn and unleavened-bread laws of Exo 13:1–16, the statute at Marah, Exo 15:25). The law of redemption precedes the law of the mountain. The pre-Christ Hebrew witnesses at this verse match the Masoretic Text.

Then the date itself, and it is more than a date: הַחֹדֶשׁ הַזֶּה לָכֶם רֹאשׁ חֳדָשִׁים רִאשׁוֹן הוּא לָכֶם — "this month shall be for you the head of months; it is the first for you" (Exo 12:2). The designation is doubled and emphatic: H7218 רֹאשׁ ("head, chief," 600 occurrences) followed by H7223 רִאשׁוֹן ("first," ordinal, 181 occurrences). Redemption does not merely begin a new year; it resets the structure of time. The month is Abib (H24 אָבִיב, "fresh grain," the pre-exilic name, Exo 13:4; Deu 16:1), called Nisan after the exile (Neh 2:1; Est 3:7). The older Near Eastern reckoning began the year in autumn; YHWH now commands Israel to count its months from deliverance. The clock starts at the blood.

There may be a deeper echo here, and it must be labeled as exactly that. The root ראש of "head" and "first" (H7218, H7223) is cognate with the רֵאשִׁית of Gen 1:1, בְּרֵאשִׁית ("in the beginning"). The structural analogy is suggestive: creation establishes the first week, and redemption establishes the first month. But the link is a root cognate plus structural parallel, not a shared lexeme — the "first/head" word of Gen 1:1 does not itself reappear here. This suggests a new-creation resonance — redemption as the world begun again — but it is a possible echo, not a demonstrable pattern, and the text does not press it.

The Lamb: Unblemished, Substitute, Eaten

On the tenth of the month, each man takes שֶׂה לְבֵית־אָבֹת, שֶׂה לַבָּיִת — "a lamb for the father's house, a lamb for the house" (Exo 12:3; H7716 שֶׂה, "lamb, small livestock," 47 occurrences across 39 verses). A Qumran Exodus manuscript preserves the double שה. If a household is too small to consume a whole lamb, neighbors join: אִישׁ לְפִי אָכְלוֹ תָּכֹסּוּ עַל־הַשֶּׂה — "each according to what he eats you shall count for the lamb" (Exo 12:4). The grammar is load-bearing. The lamb is the fixed point; the human souls (נֶפֶשׁ, H5315) are counted around it. This is positional, substitutionary coverage — every soul under the lamb is included, with no test of individual worth. The single condition is to be inside the marked house, made explicit later: none shall go out the door until morning (Exo 12:22).

The three criteria follow: שֶׂה תָמִים זָכָר בֶּן־שָׁנָה — "a lamb, unblemished, male, a year old" (Exo 12:5; confirmed by the consolidated Dead Sea Scrolls Hebrew). The qualities are (a) תָמִים (H8549, "without blemish, whole," 91 occurrences across 85 verses, 22 in Leviticus alone); (b) זָכָר (H2145, "male," the representative head); (c) בֶּן־שָׁנָה ("a year old," in its prime) — taken מִן־הַכְּבָשִׂים (from the sheep) or מִן־הָעִזִּים (from the goats). Here is the tightest co-occurrence in the study: H7716 and H8549 share exactly one verse in the entire Hebrew canon — Exodus 12:5. Of forty-seven occurrences of "lamb" and ninety-one of "unblemished," they meet only here. This is the sole text where both the species and the wholeness standard are specified for the same animal — and the whole Levitical system inherits that standard from this verse (Lev 1:3, 10; 3:1, 6; 4:3, 23, 28, 32; Num 28:3, "year-old lambs without blemish"). The Passover lamb does not satisfy the sacrificial code; it inaugurates it, since Exodus 12 precedes Sinai. The Septuagint renders תָמִים as τέλειον ("perfect, complete"; πρόβατον τέλειον, Exo 12:5) — the bridge that carries the standard into the New Testament's ἄμωμος (1 Pet 1:19).

The lamb is also a price. The Passover animal is bound by word association to the redemption of the firstborn: the lamb is the substitute by which a firstborn son is bought back — פָּדָה (H6299) with a שֶׂה (Exo 13:13; 34:20). This ties straight to Part 4: the male lamb dies in the place of the male firstborn, because Israel is YHWH's firstborn (Exo 4:22). The substitution is the same logic at two scales — one lamb for one house, one lamb for one son.

The animal is kept until the fourteenth and then slaughtered by כֹּל קְהַל עֲדַת־יִשְׂרָאֵל ("the whole assembly of the congregation," Exo 12:6) בֵּין הָעַרְבָּיִם ("between the two evenings," H6153 in the dual) — the afternoon of 14 Nisan. The precise hour was later disputed (mid-afternoon against sunset); a Second Temple reading takes the mid-afternoon position (treated below). The whole congregation slaughters: the act is corporate, as the scope of the deliverance will be.

The meal matches the night. The lamb is roasted with fire (צְלִי־אֵשׁ), explicitly not raw (נָא, H4995) and not boiled in water (Exo 12:9); head, legs, and inner parts together — the animal whole. It is eaten with מַצּוֹת (unleavened bread, H4682) and מְרֹרִים (bitter herbs, H4844, Exo 12:8). Nothing is left until morning; the remainder is burned with fire (Exo 12:10) — the no-remainder rule marks the lamb as a sacrifice, not a supper (cf. Lev 7:15–17). Then the posture: מָתְנֵיכֶם חֲגֻרִים — "your loins girded, your sandals on your feet, your staff in your hand," eaten בְּחִפָּזוֹן, "in haste" (Exo 12:11). It is eaten in the clothes of departure: a feast of exodus, not of settlement.

That word for haste traces a deliberate arc. חִפָּזוֹן (H2649) occurs only three times in the canon, and in canonical order they tell a story: Exodus 12:11, the first Passover eaten in haste; Deuteronomy 16:3, where the unleavened bread permanently memorializes "the bread of affliction, for in haste you came out of Egypt"; and Isaiah 52:12, where the new exodus is promised explicitly not in haste — כִּי לֹא בְחִפָּזוֹן תֵּצֵאוּ, "for you shall not go out in haste," with YHWH going before and behind as vanguard and rearguard. A three-occurrence word used in canonical sequence to establish urgency, memorialize it, then deliberately negate it is literary architecture, not coincidence — a strong pattern. The first deliverance was a flight; the last will be a procession. The verse closes by naming the feast for the first time with the noun: פֶּסַח הוּא לַיהוָה, "it is the Passover of YHWH" (Exo 12:11; H6453, the noun that the Septuagint will transliterate as πάσχα). That hands directly into the verb-study at the chapter's center. But before the blood, the lamb already stands in a line that runs the length of the canon — provided at Moriah, slaughtered at the exodus, led to the slaughter in Isaiah, named at last in the Gospels.

The Blood, the Sign, the Seeing

Here is the title section. It settles what the blood is and who it is for; the section after it settles what YHWH does about it.

First the application. וְלָקְחוּ מִן־הַדָּם וְנָתְנוּ עַל־שְׁתֵּי הַמְּזוּזֹת וְעַל־הַמַּשְׁקוֹף — "they shall take some of the blood and put it on the two doorposts and on the lintel" (Exo 12:7). The blood (H1818) goes on the two doorposts (H4201 מְזוּזָה, dual; 19 occurrences) and the lintel (H4947 מַשְׁקוֹף — a word that occurs only three times in the whole Old Testament: Exo 12:7, 22, 23). The architecture is precise: left post, right post, lintel — three sides framing the opening. The threshold is not marked. Verse 22 confirms it: the blood sits in the basin (H5592) at the threshold, but it is applied upward to the frame with a bundle of hyssop (אֲזוֹב, H231). You pass through the blood-marked opening; you never tread on the blood. The instrument, hyssop, is the purification plant of Leviticus 14, Numbers 19, and Psalm 51:7, and it reappears at the cross (Jhn 19:29) — a link the next passage develops.

Then the judgment is announced. וְעָבַרְתִּי בְאֶרֶץ־מִצְרַיִם בַּלַּיְלָה הַזֶּה וְהִכֵּיתִי כָל־בְּכוֹר — "I will pass through (H5674) the land of Egypt this night and strike every firstborn" (Exo 12:12). And the reason behind the reason: וּבְכָל־אֱלֹהֵי מִצְרַיִם אֶעֱשֶׂה שְׁפָטִים אֲנִי יְהוָה — "against all the gods of Egypt I will execute judgments; I am YHWH." The word שְׁפָטִים (H8201, 16 occurrences, eight of them in the Exodus–Numbers narrative) is the formal term for YHWH's verdict-acts; Numbers 33:4 closes the loop ("against their gods YHWH executed judgments"). The plagues are a structured legal polemic against Egypt's pantheon — though the matching of each plague to a specific Egyptian deity is historical reconstruction, an inference, not a claim the text itself makes. What the text makes is the signature: אֲנִי יְהוָה, "I am YHWH." Judgment and self-revelation are one act. This verse introduces עָבַר; hold the verb here, and let the next section disambiguate it.

Now the spine verse, 12:13, and three observations carry it.

First, the blood is a sign — not merely like one. The construction is לְאֹת, "for a sign," with no article: the blood does not point to a sign; the blood is the sign (H226 אוֹת). And the pairing is unique: H226 "sign" and H1818 "blood" co-occur in exactly two verses in the entire canon — Exodus 12:13 and Exodus 4:9, the earlier sign where the Nile water poured out becomes blood on dry ground (Exo 4:9). Of three hundred sixty occurrences of "blood" and eighty of "sign," they meet only twice, both in Exodus. This sets the Passover blood within the canon's covenant-sign series — the rainbow (Gen 9:12–13), circumcision (Gen 17:11), the Sabbath (Exo 31:13), all bearing H226 — yet distinguishes it: the Passover sign is applied not to the sky, not to the body, but to the house. The protection is positional and corporate, gathered around a doorway. And this externally-applied blood (H1818) opens a trajectory: at Sinai the same blood is dashed on the people to ratify the covenant — דַם־הַבְּרִית, "the blood of the covenant" (H1818 + H1285, Exo 24:8) — and that is the phrase Jesus takes up over the cup, "this is my blood of the covenant" (Mat 26:28). The blood that shelters the house and the blood that seals the covenant are one stream.

Second, the sign is for God to see. הַדָּם לָכֶם לְאֹת — "the blood shall be for you a sign" — and the verse names at once whose perception activates it: וְרָאִיתִי, "and when I see." The verb is H7200, Qal perfect first-person singular with the sequential waw, "when I see." The blood is on the outside of the door; the family inside cannot see it. It is not their badge of faith, not a display, not even something they look upon — it is the objective trigger that YHWH himself reads. And the construction is the very one used at Gen 9:16: וּרְאִיתִיהָ לִזְכֹּר בְּרִית עוֹלָם, "and I will see it [the rainbow] to remember the everlasting covenant" — the same H7200 Qal perfect first-person singular with sequential waw in both verses (at Gen 9:16 carrying a third-feminine-singular object suffix, "it," for the bow). The mechanic is identical: a visible sign on a surface, YHWH sees it, YHWH acts protectively. This is the connection to Part 8: what YHWH sees is what divides. At Goshen the distinction was geographic; here it is the blood, and it is YHWH's seeing that enacts it.

Third, the outcome. וְלֹא־יִהְיֶה בָכֶם נֶגֶף לְמַשְׁחִית — "no plague (H5063 נֶגֶף, 7 occurrences) shall be among you to destroy" (לְמַשְׁחִית, H4889); 12:23 makes the act explicit.

Two Verbs, Two Acts: Strike and Shelter

This is the exegetical heart of the study, and it rests on a single claim: פָּסַח does not mean merely skip; it means shelter. The case must be built honestly, in three moves — first the two distinct verbs, then the concession that the word's neighborhood favors "limp," then the evidence that carries it to "shelter."

Two verbs, one verse. The most common misreading treats H5674 עָבַר and H6452 פָּסַח as synonyms — two ways of saying the same skip. But the chapter sets them side by side: וְעָבַר יְהוָה לִנְגֹּף אֶת־מִצְרַיִם ... וּפָסַח יְהוָה עַל־הַפֶּתַח — "YHWH will pass through (עָבַר) to strike Egypt ... and YHWH will pass over (פָּסַח) the door" (Exo 12:23). H5674 is the ordinary verb of spatial passage; it carries no protective sense — it is the movement of the stroke. H6452 is the verb the feast is named for, and here it takes the preposition עַל, "over, upon" the door — the movement of protection. Same agent, one night, two motions.

The destroyer belongs to this verse too: וְלֹא יִתֵּן הַמַּשְׁחִית לָבֹא אֶל־בָּתֵּיכֶם — "he will not let the destroyer (הַמַּשְׁחִית, H7843, 'the destroying one') enter your houses" (Exo 12:23). The destroyer is not an independent power at war with YHWH; he is YHWH's own agency of destruction, deployed against Egypt and restrained from the blood-marked house by YHWH's own passing over — one God, executing judgment and extending mercy through one sign. The New Testament names the same agent (ὁ ὀλοθρεύων τὰ πρωτότοκα, "the destroyer of the firstborn," Heb 11:28). Part 11 raised how YHWH's own going-out (Exo 11:4) squares with "the destroyer"; the harmonization — one principal, one restrained agent — is an inference, and 12:23 is where the text most nearly states it.

The neighborhood favors "limp" — say so. Honesty comes first; refusing false balance does not mean refusing the evidence that cuts against you. The other occurrences of H6452 are physical and unflattering: פֹּסְחִים, the people "limping between two opinions" (1Ki 18:21); the prophets of Baal performing their ritual limp around the altar (1Ki 18:26); Mephibosheth who "became lame" (2Sa 4:4). Its semantic neighbors are the words for lameness and tottering. The root denotes an irregular, lurching motion. So the protective reading cannot rest on the word's lexical neighborhood — and any honest study must concede that. The real question is whether YHWH's act means hop over (skip the house) or hover over (shelter the house). That question is not settled by the root. It is settled by two pieces of external evidence.

Isaiah 31:5 — the internal Old Testament evidence. כְּצִפֳּרִים עָפוֹת כֵּן יָגֵן יְהוָה צְבָאוֹת עַל־יְרוּשָׁלִָם ... גָּנוֹן וְהִצִּיל פָּסֹחַ וְהִמְלִיט — "as birds hovering, so YHWH of hosts will shield Jerusalem; shielding and delivering, passing over and rescuing" (Isa 31:5). Here פָּסֹחַ (the same root H6452, in the infinitive absolute) stands in synonymous parallelism with גָּנוֹן (H1598, "to shield, cover, protect") — not with עָבַר. Hebrew parity-parallelism assigns paired verbs the same semantic weight; the image is a mother bird hovering over the nest (compare Deu 32:11). And פָּסֹחַ is coupled with הִמְלִיט ("rescue") exactly as Exodus 12:27 couples פָּסַח with הִצִּיל. This is not later reading-back: the Great Isaiah Scroll preserves the four-verb sequence intact, the oldest Hebrew witness confirming that "passing over" sat among the shelter-words centuries before Christ.

The Septuagint — the pre-Christian Greek reading. Where the protection is stated in the first person and in the memorial, the Greek translators chose σκεπάζω ("cover, shelter"): σκεπάσω ὑμᾶς, "I will shelter you" (Exo 12:13); ὡς ἐσκέπασεν τοὺς οἴκους, "as he sheltered the houses" (Exo 12:27); and at Isaiah 31:5, ὑπερασπίζω, "to hold a shield over." One verse runs against the grain and must be named: at 12:23 the Greek uses παρέρχομαι twice — for both the striking and the passing over the door (καὶ παρελεύσεται κύριος τὴν θύραν), rendering even the protective act as a passing-by. But the weight of the oldest Greek witness falls on covering, not skipping.

The chapter then glosses itself. זֶבַח־פֶּסַח הוּא לַיהוָה אֲשֶׁר פָּסַח עַל־בָּתֵּי בְנֵי־יִשְׂרָאֵל ... וְאֶת־בָּתֵּינוּ הִצִּיל — "it is the sacrifice of the Passover to YHWH, who passed over the houses of the sons of Israel ... and delivered our houses" (Exo 12:27). H6452 פָּסַח and H5337 הִצִּיל ("delivered," Hiphil) are joined in one clause. These are not two acts. The passing-over is the deliverance, just as Isaiah 31:5 said.

The verdict, then, and no false balance: both senses are present, and they are two faces of one event. The destroyer passes over (bypasses) the marked houses; YHWH hovers over (shelters) them. The derivation from "limp/hop" describes the motion of the foot; Isaiah 31:5 and the Septuagint establish the theological weight as protection. And this is exactly why the blood is more than an escape clause: because the blood brings YHWH's sheltering presence over the house, the New Testament can read the Passover as atonement — God placing himself between his people and the judgment — not mere exemption from a passing danger.

Unleavened Bread, the Memorial, and the Cut-Off Soul

The night is to be kept forever. וְהָיָה הַיּוֹם הַזֶּה לָכֶם לְזִכָּרוֹן — "this day shall be for you a memorial" (Exo 12:14; H2146 זִכָּרוֹן, 24 occurrences), kept as a חַג ("pilgrimage feast") and a חֻקַּת עוֹלָם ("a statute forever"). The redemption day is fixed at the head of all time, and the reset of the calendar (the first section) is made perpetual liturgy. The ordinance reaches even into prophetic vision: Ezekiel's restored temple keeps it by the same measures — "in the first month, on the fourteenth day of the month, you shall have the Passover (הַפָּסַח), a feast of seven days; unleavened bread (מַצּוֹת) shall be eaten" (Ezk 45:21) — the same first-month dating, the same fourteenth day, the same seven-day מַצּוֹת. What is founded in Egypt is still being kept in the prophet's last vision of worship.

With it comes the seven-day feast of unleavened bread. The lamb is eaten with מַצּוֹת (H4682, 53 occurrences), the bread of haste — "the bread of affliction, for in haste you came out of Egypt" (Deu 16:3). For seven days שִׂבְעַת יָמִים all leaven must be purged: תַּשְׁבִּיתוּ שְּׂאֹר מִבָּתֵּיכֶם, "you shall put away leaven (שְׂאֹר, H7603) from your houses" (Exo 12:15), and no חָמֵץ (leavened bread, H2557) is to be found in them (Exo 12:19). The Torah already binds blood and leaven together — "you shall not offer the blood of my sacrifice with leaven" (Exo 23:18; 34:25) — so the pairing is native to the ordinance, not a later metaphor laid over it.

The terms are absolute. כָּל־אֹכֵל חָמֵץ וְנִכְרְתָה הַנֶּפֶשׁ הַהִוא — "anyone who eats leavened bread, that soul shall be cut off" (Exo 12:15, 19; H3772 כָּרַת in the Niphal + H5315 נֶפֶשׁ). This is the karet penalty, the gravest communal sentence short of execution. Within Exodus the karet-of-the-soul formula falls in exactly three places: 12:15, 12:19, and 31:14 — the Sabbath. Passover and Sabbath stand together as the two observances whose violation cuts a soul off from the people. The feast of redemption cannot be half-kept. And it binds the גֵּר (the resident alien) as much as the native-born (Exo 12:19): the shelter is open to the stranger, but its terms are not optional for anyone.

Paul reads the ordinance exactly along its own grain. ἐκκαθάρατε τὴν παλαιὰν ζύμην ... καὶ γὰρ τὸ πάσχα ἡμῶν ὑπὲρ ἡμῶν ἐτύθη Χριστός — "Cleanse out the old leaven ... for our Passover, Christ, has been sacrificed" (1 Cor 5:7). The Greek bridge is clean: the Septuagint renders מַצָּה as ἄζυμος and both Hebrew leaven-words as ζύμη. Paul's logic mirrors the chapter's: because the Passover is accomplished, live unleavened — the physical purge of Exodus 12:15 becomes the moral posture of the church, ἑορτάζωμεν ... ἐν ἀζύμοις εἰλικρινείας καὶ ἀληθείας, "let us keep the feast ... with the unleavened bread of sincerity and truth" (1 Cor 5:8). This is a probable allusion approaching strong pattern — built on a Torah linkage, embedded in an explicit identification, carried by a confirmed lexical bridge. One honest caveat: the single Greek word ζύμη does not preserve the Hebrew distinction between שְׂאֹר and חָמֵץ; Paul takes the moral force of leaven, not its food-chemistry.

A Second Temple Reading: Wisdom, Jubilees, and the Great Passovers

These are historical witnesses to how Second Temple Jews read the Passover — valuable for background and reception, not authoritative on the level of the canon. Three brief windows.

The Wisdom of Solomon (deuterocanonical, written in Greek around 100–50 BC) gives the sharpest ancient gloss. At its account of the tenth plague, God's ὁ παντοδύναμός σου λόγος, "your all-powerful Word," leaps from the heavenly throne as ἀπότομος πολεμιστής, a "fierce warrior" bearing a sharp sword (Wisdom 18:14–16) — a pre-Christian Jewish personification of the agent of death as the divine Word. And the book names that agent ὁ ὀλεθρεύων, "the destroyer" (Wisdom 18:25) — the very term-of-art the New Testament will use (Heb 11:28). Most strikingly, Wisdom reads the exodus as a new creation and describes Israel as σκεπαζόμενοι, "sheltered," by God's hand (Wisdom 19:6–8) — the same σκεπάζω verb the Septuagint used for the Passover protection at Exodus 12:13, here extended to the sheltering at the Red Sea, and it then calls the redeemed ἀμνοί, "lambs" (Wisdom 19:9). This is the strongest external confirmation of the shelter reading: σκεπάζω was the established Second Temple word for YHWH's Passover protection.

Jubilees (pseudepigraphal, c. 160–150 BC) preserves the blood as the saving sign on the lintels (Jubilees 49:3), attests wine at the Passover meal (49:6 — pre-Christian evidence for what Jesus had to hand at the Last Supper), and places the slaughter in the mid-afternoon (49:10). It is background only, but it shows the feast's furniture already in place before the Gospels.

And the canon itself records a Passover kept by the unqualified. At Hezekiah's great Passover, many ate who had not cleansed themselves, and the king prayed that YHWH would "make atonement for everyone who sets his heart to seek God," even apart from the purity of the sanctuary — and YHWH "heard Hezekiah and healed the people" (2 Chr 30:18–20). The ground Hezekiah names is the heart set to seek God, not ritual perfection — "everyone who sets his heart to seek God ... though not according to the purification of the sanctuary" (2 Chr 30:19). The lamb was unblemished; the people sheltered under it were not.

The Lamb Through the Canon

Three claim-types must be kept distinct here, and not flattened into one word "fulfillment": a lexical link, a typological role-for-role correspondence, and an explicit New Testament identification.

The Septuagint makes πάσχα the inherited word. It transliterates H6453 פֶּסַח as πάσχα (G3957, Exo 12:11), and the word passes straight into the New Testament (1 Cor 5:7; Heb 11:28; Luk 22:15). The feast carries the same name in both testaments.

But the lamb-words diverge deliberately. The Septuagint of Exodus 12:3, 5 uses πρόβατον (G4263) for the Passover animal. The New Testament chooses a different word for Jesus — ἀμνός (G286): ἴδε ὁ ἀμνὸς τοῦ θεοῦ, "Behold the Lamb of God" (Jhn 1:29) — and ἀμνός is the Septuagint word at Isaiah 53:7. So John the Baptist's cry is a combined Passover-and-Suffering-Servant identification, and Acts 8:32 quotes Isaiah 53:7 in Greek and applies it directly to Christ. Then 1 Peter 1:19 — ἀμνοῦ ἀμώμου καὶ ἀσπίλου, "a lamb without blemish and without spot" — maps ἄμωμος (G299) onto תָמִים (H8549), the Passover criterion of the unblemished lamb: a lexical link. Revelation switches again to ἀρνίον (G721, the diminutive, used 29 times in Revelation) — the Lamb standing as though slain, ὡς ἐσφαγμένον (Rev 5:6), echoing the Passover slaughter. And Revelation gathers the whole arc into one image of triumph: the redeemed beside the sea of glass sing "the song of Moses, the servant of God, and the song of the Lamb (τοῦ ἀρνίου)" (Rev 15:3) — the Exodus deliverance-song (Exo 15) and the Lamb's song are one song at the end, sung after the last plagues, by a people brought through a final sea. The New Testament does not mechanically copy the Septuagint's Exodus vocabulary; it selects among the lamb-words to make specific connections.

Name the three claim-types plainly. The explicit identification is 1 Corinthians 5:7: τὸ πάσχα ἡμῶν ... Χριστός, "Christ is our Passover." Paul makes it categorical; this is the one place to say "Christ is the Passover" without hedging. The typological correspondence is role-for-role: a victim, unblemished; slaughtered; blood applied; the household sheltered from the destroyer. The roles are strictly analogous across both testaments (1 Pet 1:18–19; Heb 11:28). This is strong recurrence and structural fit — but it is distinct from a formal prophecy-fulfillment citation of this passage. And the shelter payoff is the third: because פָּסַח is sheltering, the New Testament reads the blood as atonement — the blood brings God's protective presence — not mere exemption. That is why "Christ our Passover" carries the weight of salvation, not merely of the calendar.

One note for precision. The bone-not-broken citation of John 19:36 draws on Exodus 12:46 and Numbers 9:12, which lie outside this passage (12:1–20); it belongs to the study of the next section. And the Last Supper, where Jesus reauthors the feast around himself (Luk 22:7–20), is the frame in which the πάσχα becomes his own body and blood.

Conclusion

Return to the doorpost and to the title. The blood is on the outside of the house, where the family cannot see it — and that is the point: it is a sign for God. "When I see the blood, I will pass over you" (Exo 12:13). The whole weight of the night rests not on the quality of Israel's faith or fear but on YHWH's seeing and YHWH's sheltering. The lamb was unblemished; the family inside was not. What saved them was being under the blood that YHWH reads. The destroyer passed through Egypt; YHWH hovered over Israel. The Passover was never mere escape — it was God placing himself, by the sign of blood, between his people and the judgment he himself executed. That is why the New Testament could look at a slaughtered lamb and say, without strain, "Christ our Passover" (1 Cor 5:7).
