And if any of the flesh of the offering or of the bread is over till the morning, let it be burned with fire; it is not to be used for food, for it is holy.
Take no leavened bread with it; for seven days let your food be unleavened bread, that is, the bread of sorrow; for you came out of the land of Egypt quickly: so the memory of that day, when you came out of the land of Egypt, will be with you all your life.
For seven days let no leaven be used through all your land; and nothing of the flesh which is put to death in the evening of the first day is to be kept through the night till morning.
