Parallel
Exodus 12:17
Clementine Vulgate · Berean Standard Bible
Et observabitis azyma : in eadem enim ipsa die educam exercitum vestrum de terra Ægypti, et custodietis diem istum in generationes vestras ritu perpetuo.
So you are to keep the Feast of Unleavened Bread (note: That is, the seven-day period after the Passover during which no leaven may be eaten), 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.
