16On the first day you are to hold a sacred assembly, and another on the seventh day. You must not do any work on those days, except to prepare the meals— that is all you may do.
17So you are to keep the Feast of Unleavened Bread, for on this very day I brought your divisions out of the land of Egypt. You must keep this day as a permanent statute for the generations to come.
— Exodus 12:16-17
