Deuteronomy 16:2–8

²You shall offer the Passover sacrifice to the Lord your God from the flock and the herd, at the place that the Lord will choose as a dwelling for his name.^{* 3}You must not eat with it anything leavened. For seven days you shall eat unleavened bread with it—the bread of affliction—because you came out of the land of Egypt in great haste, so that all the days of your life you may remember the day of your departure from the land of Egypt.^{* 4}No leaven shall be seen with you in all your territory for seven days, and none of the meat of what you slaughter on the evening of the first day shall remain until morning.^{* 5}You are not permitted to offer the Passover sacrifice within any of your towns that the Lord your God is giving you. ⁶But at the place that the Lord your God will choose as a dwelling for his name, only there shall you offer the Passover sacrifice, in the evening at sunset, the time of day when you departed from Egypt.^{* 7}You shall cook it and eat it at the place that the Lord your God will choose; the next morning you may go back to your tents.^{* 8}For six days you shall continue to eat unleavened bread, and on the seventh day there shall be a solemn assembly for the Lord your God, when you shall do no work.^*
