Deuteronomy 16
2 Ref The Passover offering, from your flock or your herd, is to be given to the Lord your God in the place marked out by him as the resting-place of his name.
3 Ref 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.
4 Ref 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.
5 Ref The Passover offering is not to be put to death in any of the towns which the Lord your God gives you:
6 Ref But in the place marked out by the Lord your God as the resting-place of his name, there you are to put the Passover to death in the evening, at sundown, at that time of the year when you came out of Egypt.
