דברי הימים א, פרק ט״ז, פסוק ט״ו

Memory serves as the foundation of the eternal bond between God and Israel. The people are called to constantly hold in their minds the everlasting connection and the decrees established between them and God. This obligation to remember is absolute, as the relationship and the covenant endure forever [רד״ק, ביאור שטיינזלץ].

At the heart of this memory is a specific covenant, though commentators differ on its exact nature. One approach understands this covenant as the Torah itself, which was given to the Israelites as a binding agreement [רש״י, מצודת דוד]. Another perspective traces the covenant further back in history to Abraham. In this view, the focus is on the specific promises God made to him during the Covenant of the Pieces, which He faithfully kept for Abraham's descendants. Accordingly, the divine command is understood not as a set of laws, but rather as a firm decree and promise that God established [רד״ק].

The timeline of this promise is described as enduring for a thousand generations, a concept understood in two distinct ways. It can be seen as a general expression of pure eternity, ensuring that the relationship lasts for all future eras [ביאור שטיינזלץ], or as a specific guarantee that the decree established with Abraham will remain valid for exactly a thousand generations [רד״ק]. Alternatively, the number relates directly to the timing of the Torah's delivery. According to this explanation, God's original plan was to wait a full thousand generations after the creation of the world before giving the Torah. However, recognizing that the world simply could not survive without it, He chose to skip nine hundred and seventy-four generations, ultimately presenting the Torah to humanity after only twenty-six generations [רש״י, מצודת דוד].
