ירמיהו, פרק ל״ב, פסוק מ׳

The relationship between God and His people ultimately reaches a stage of absolute permanence. It transforms into an unbreakable bond that is no longer fragile or conditional, but rather founded entirely on a divine promise. The primary approach among commentators is that this eternal covenant represents a permanent commitment from which God will never withdraw. As part of this lasting agreement, God guarantees that He will never step away from His people and will continually provide them with goodness [מצודת דוד, ביאור שטיינזלץ].

To ensure the success of this relationship, the commitment must be mutual. God promises to plant a deep sense of reverence within the hearts of the people, ensuring that they, too, will never stray from His path [מצודת דוד, ביאור שטיינזלץ].

The [מלבי״ם] highlights a profound cause-and-effect relationship within this promise, explaining the exact mechanism that makes the covenant eternal. Because this new agreement is absolute and unconditional, God must eliminate the single factor that could potentially destroy it: human sin. By instilling reverence directly into the hearts of the people, God actively prevents them from sinning and turning away from Him. This creates a perfect, self-sustaining cycle. The people embrace a genuine awe of God, and He protects them from sin so that the agreement remains intact. Consequently, the covenant endures forever, allowing God to continuously and wholeheartedly bestow His goodness upon them.
