This verse acts as a formal introduction to a new set of divine laws. Commentators note the location is Succoth, Israel's first stop after the Exodus. While the verse itself is simple, it signals the start of a foundational teaching for the newly freed nation: the consecration of the firstborn. This instruction, which follows immediately, was designed to perpetually remind Israel of their deliverance from Egypt and their special status as a people redeemed by God.
