Hebrew Key Terms:
Context: Jeremiah 31:31-34 is the single most important new-covenant text in the OT and the most quoted OT passage in the New Testament (cited in full at Heb 8:8-12 and again substantially at Heb 10:16-17). The oracle sits in the "Book of Consolation" (Jer 30-33), a cluster of restoration prophecies that promise Israel's return from exile and an eschatological covenantal renewal. The immediate setting is the final decades before Jerusalem's 586 BC destruction; the audience is a people watching the Sinai covenant collapse under their own covenantal unfaithfulness (Jer 11 makes explicit the charge that Israel has broken the bᵉrîṯ made at the Exodus). Against this backdrop, YHWH declares: "Behold, the days are coming, declares the LORD, when I will make a new covenant (*bᵉrîṯ ḥădāšâ) with the house of Israel and the house of Judah — not like the covenant I made with their fathers on the day I took them by the hand to bring them out of the land of Egypt, my covenant that they broke, though I was their husband."* (vv. 31-32). The new covenant is defined by four features that distinguish it from the Sinai covenant: (1) Interiorized Torah — "I will put my law (*tôrâ) within them, and I will write (eḵtᵉḇennâ) it on their hearts"* (v. 33). The Sinai Torah was written on stone tablets and placed outside the people; the new-covenant Torah is written inside them. (2) Covenantal formula — "I will be their God, and they shall be my people" (v. 33) — the ancient covenantal language now reaches its definitive realization. (3) Universalized knowledge — "And no longer shall each one teach his neighbor and each his brother, saying, 'Know the LORD,' for they shall all know me, from the least of them to the greatest" (v. 34a). Mediated covenantal knowledge is replaced by universal direct knowledge. (4) Decisive forgiveness — "For I will forgive their iniquity, and I will remember their sin no more" (v. 34b). The climactic final phrase is the covenant's foundational provision: all the other features (interiorized Torah, covenantal formula, universal knowledge) rest on a definitive, unrepeatable forgiveness that removes sin from God's memory. The oracle ends with kî ("for"), grounding everything preceding on the final forgiveness clause — forgiveness is the engine that makes the new covenant possible.

Christological Connection: Jeremiah 31:31-34's theological meaning in its own context is the definitive divine commitment to replace the broken Sinai covenant with a qualitatively new arrangement, whose innovations converge on a single engine: unrepeatable divine forgiveness. Interiorized Torah, the covenantal formula, and universal direct knowledge of God are all downstream of the foundational kî clause — "for I will forgive their iniquity, and I will remember their sin no more." The crucial OT problem the passage solves is the sacrificial system's annual repetition. Leviticus 16 records that on the Day of Atonement the high priest made atonement "for the Holy Place, because of the uncleannesses of the people of Israel and because of their transgressions, all their sins" (Lev 16:16), but the rite was annual (Lev 16:34) — every year the sanctuary needed re-cleansing, and every year the people's sins had to be atoned for anew. Hebrews later articulates what Jer 31 implies: the Levitical rite was a yearly reminder of sin (Heb 10:3), not its removal. Jeremiah's promise shatters this limitation: in the new covenant, God will not remember sin. Covenantal non-remembrance is not divine forgetfulness (God is not finite); it is a judicial declaration that sin has been so definitively dealt with that it will never rise again as ground for divine action against the sinner. The prophet promises what the Levitical system could not deliver: unrepeatable, judicially final forgiveness — and with it, the interior transformation that forgiveness alone makes possible.
The Christological significance is that Jesus Christ both claims and inaugurates this new covenant with explicit verbal precision at the Last Supper. "This cup is the new covenant in my blood, which is poured out for you" (Luke 22:20; cf. 1 Cor 11:25). Matthew and Mark make the sacrificial connection explicit: "this is my blood of the covenant, which is poured out for many for the forgiveness of sins" (Matt 26:28) — the new covenant's forgiveness (Jer 31:34) secured by the covenantal blood (Exod 24:8) of the one Servant whose nefeš makes atonement (Isa 53:10; Lev 17:11). Jesus gathers three OT trajectories into one cup: the Sinai covenant's inaugurating blood, the Levitical system's atoning blood, and Jeremiah's new-covenant promise. All three converge at Calvary.
Hebrews 8:8-12 and Hebrews 10:15-18 then make the fulfillment explicit and programmatic. The writer of Hebrews quotes Jer 31:31-34 in full at Heb 8:8-12 — the longest OT citation in the NT — as the hermeneutical key to the entire priestly argument of Heb 7-10. The point of the citation at Heb 8 is that Christ is the mediator of a better covenant (v. 6) precisely because that covenant was already announced by God Himself as superseding the first (vv. 7-13). Then at Heb 10:15-18, the writer re-cites the decisive forgiveness clauses of Jer 31:33-34 and concludes with the climactic deduction: "Where there is forgiveness of these, there is no longer any offering for sin" (Heb 10:18). This verse is the logical endpoint of the entire sacrificial trajectory. Jeremiah's non-remembrance promise is precisely the sacrificial system's functional termination — where sins are not remembered, no offering needs to be offered. The Levitical system has reached its telos in Christ's one offering; the new covenant's forgiveness is the proof.
The escalation is structural and comprehensive. Sinai's covenant was inaugurated with the blood of bulls (Exod 24:8); the new covenant is inaugurated with the blood of the eternal Son (Heb 9:14; Heb 13:20 — "the blood of the eternal covenant"). Sinai's Torah was external on stone; the new covenant's Torah is internal on the heart (2 Cor 3:3 — "written not with ink but with the Spirit of the living God, not on tablets of stone but on tablets of human hearts"). Sinai required mediated knowledge; the new covenant gives universal direct knowledge through the Spirit (1 John 2:27 — "the anointing that you received from him abides in you, and you have no need that anyone should teach you"). Sinai's forgiveness was annually repeated and provisional; the new covenant's forgiveness is ephapax and definitive — "I will remember their sin no more" is grammatically and theologically permanent.
The already/not-yet structure is explicit in the NT's reception. Already: the new covenant has been inaugurated at the Last Supper and ratified in Christ's blood at Calvary; believers now have "forgiveness of sins" in His name (Acts 10:43; Eph 1:7); the Torah has been written on the hearts of those who have received the Spirit (2 Cor 3; Rom 8); the knowledge of God has begun to go forth universally through the gospel. Not yet: the new covenant's universal-knowledge clause ("they shall all know me, from the least of them to the greatest") awaits its eschatological consummation when "the earth shall be full of the knowledge of the LORD as the waters cover the sea" (Isa 11:9; Hab 2:14); the covenantal formula will receive its final realization when "the dwelling place of God is with man… and God himself will be with them as their God" (Rev 21:3) — the new-covenant formula becomes the new-creation reality.
Connection Method(s): Promise-Fulfillment (primary) — Jer 31:31-34 is a verbal divine commitment, not a typological structure, and its fulfillment is verbally and explicitly claimed by Christ ("the new covenant in my blood," Luke 22:20) and by Hebrews (which cites the text in full and argues from it at Heb 8 and Heb 10). This is Promise-Fulfillment in its most formal sense: God speaks a promise, names its content, and later declares it fulfilled in a specific historical-redemptive event. Longitudinal Theme — Jer 31 is a central station in the Covenant theme and the Sacrifice and Atonement theme, where the promise of final forgiveness rests on a sacrifice yet to come. Redemptive-Historical Progression — the oracle marks the decisive inflection point between the Mosaic administration's provisional covenantal arrangement and the new covenant's definitive one; it stands in Jeremiah's career as the hinge between the collapsing old order and the promised new order, and in the canon as the OT's most explicit anticipation of the gospel's covenantal content. Typology is not the primary lens (anti-default check): Jer 31 does not operate by prefigurative correspondence (a historical person or event corresponding to Christ through analogical escalation); it operates by verbal promise — YHWH says He will forgive and says He will write Torah on hearts, and the NT says this has happened in Christ. Treating Jer 31 as typology would obscure its forensic and covenantal structure. The NT itself treats it as explicit verbal fulfillment (Heb 8:8-12; 10:15-18), not as typological shadow.
