BBE(i)
16 And on the first day there is to be a holy meeting and on the seventh day a holy meeting; no sort of work may be done on those days but only to make ready what is necessary for everyone's food.
17 So keep the feast of unleavened bread; for on this very day I have taken your armies out of the land of Egypt: this day, then, is to be kept through all your generations by an order for ever.
