ירמיהו, פרק ל״ג, פסוק כ״א

The natural world operates on an unbreakable rhythm, serving as a powerful reflection of divine promises. A direct comparison is drawn between the physical laws of nature and the spiritual commitments made by God.

This idea establishes a profound condition. It proposes that only if humanity could somehow break the cycle of day and night, disrupting the very foundation that sustains the world, could the covenant made with David ever be broken. This promise ensures that David will always have a descendant to rule on his throne.

In the exact same manner, this absolute guarantee extends to the Levite priests who serve God, ensuring their role will never cease. The primary approach among commentators is that this comparison illustrates the eternal nature of the divine promise. Just as it is beyond human ability to alter the order of creation or stop the transition from day to night, it is completely impossible for the covenant with the Davidic royal dynasty and the priesthood to ever be broken [מצודת דוד, ביאור שטיינזלץ].
