Hebrew Key Terms:
Context: The most extensive and explicit promise of a new covenant in the OT. Written during the Babylonian siege of Jerusalem, Jeremiah prophesies that despite covenant failure and exile, God will make a "new covenant" that will be internal ("on their hearts"), universal ("all shall know me"), and secure final forgiveness ("I will remember their sin no more").

Connections:
Christological Connection: Jesus inaugurated the new covenant by His blood at the Last Supper: "This cup is the new covenant in my blood" (Luke 22:20). His death secured the final forgiveness promised in Jeremiah 31:34 (Heb 10:17-18). The indwelling Holy Spirit, poured out at Pentecost, writes God's law on believers' hearts (2 Cor 3:3), enabling the obedience the Mosaic covenant demanded but could not produce. Hebrews 8-10 extensively expounds Jeremiah 31:31-34 to prove Christ is the mediator of a "better covenant" with "better promises" (Heb 8:6). The new covenant is "new" not in annulling God's moral law, but in providing internal transformation through the Spirit to fulfill what the external law could only command.
Connection Method(s): Promise-Fulfillment — Jeremiah's explicit promise of a new covenant with internal law, universal knowledge, and final forgiveness is direct messianic prophecy fulfilled in Christ's blood and the Spirit's indwelling, as Hebrews 8-10 extensively demonstrates.
