Matthew 26:28 → Exodus 24:8

At Sinai, after Israel pledged "All that the LORD has spoken we will do" (Exod 24:7), Moses sprinkled the sacrificial blood on the people and named it dam ha-berit — "the blood of the covenant that the LORD has made with you" (24:8) — the shed blood ratifying the bilateral bond between Yahweh (the altar) and Israel (the people). At the Last Supper Jesus deliberately reaches for that singular formula: "This is My blood of the covenant" (τοῦτο… ἐστιν τὸ αἷμά μου τῆς διαθήκης), reproducing the LXX phrase τὸ αἷμα τῆς διαθήκης (inserting only the possessive μου) — identifying His own blood as the covenant-ratifying blood Moses once threw on the people. The pairing is tiered Allusion rather than Direct Quotation because the formula is unmarked — woven into the words of institution, not introduced as a citation (matching the sibling Mark 14:24 pairing). The link is typological with historical escalation, not a mere thematic echo: both Sinai and Calvary are real covenant-inaugurations, but the type is escalated in every dimension — the blood of bulls becomes the Mediator's own blood, the application moves from the body to the cleansed conscience (cf. Heb 9:14), and a covenant Israel could and did break gives way to one God Himself keeps. It is Typology rather than bare Longitudinal Theme because Exod 24:8 supplies the unique source-formula (it occurs only here in the Pentateuch) and Jesus reads Himself as its fulfillment; it is also Promise-Fulfillment because Matthew fuses the Exod 24:8 phrase with the new-covenant promise of Jer 31:31-34, adding "for the forgiveness of sins" (εἰς ἄφεσιν ἁμαρτιῶν) to activate Jeremiah's "I will remember their sin no more" (this pair is scoped to the Exod 24:8 "blood of the covenant" half; the Jeremiah strand is carried by the companion IP). The telos is not that Christ merely resembles Moses, but that the blood I am invited to drink is poured out for me, for the forgiveness of sins — the covenant is no longer a contract I must keep on pain of breaking it, but a feast at which the King gives His own life to bind me to Himself forever; to behold that cup is to taste a covenant-keeping love worth wanting above all things.
