Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the LORD:
This verse specifies how the new covenant differs from the old: it is 'not according to' the Mosaic covenant made at Sinai. God identifies the problem with the old covenant: 'which my covenant they brake, although I was an husband unto them.' The issue was not God's unfaithfulness (He remained the faithful husband) but Israel's unfaithfulness (they broke the covenant). The Mosaic covenant could command but could not enable obedience; it revealed sin but could not remedy it.
The marriage metaphor is profound. God entered a covenant relationship with Israel like a husband to a wife, yet they committed spiritual adultery through idolatry. Despite God's faithfulness, Israel repeatedly violated their marriage vows. This explains why a new covenant was necessary—not because the old covenant was flawed in itself, but because Israel could not keep it due to their sinful hearts. The law was 'weak through the flesh' (Romans 8:3).
Reformed theology distinguishes between the covenant of works (do this and live) and the covenant of grace (believe and live). The Mosaic covenant contained elements of both—it demanded obedience (works) but also included provisions for sacrifice and grace. Yet it could not ultimately save because human obedience was required but impossible. The new covenant establishes salvation purely on Christ's obedience, credited to believers through faith (Romans 5:19).
Historical Context
The Mosaic covenant was given at Mount Sinai after the Exodus (Exodus 19-24). Israel repeatedly broke it through idolatry, injustice, and rebellion. The prophets frequently described Israel's unfaithfulness in marriage terms—whoredom, adultery, forsaking their husband. The exile was the ultimate consequence of covenant breaking. Yet God promised not to abandon His bride but to establish a new covenant that would succeed where the old failed.

How does the marriage metaphor help us understand covenant relationship with God?
What makes the new covenant 'not according to' the old—what fundamental difference enables it to succeed?
