Deuteronomy 16:2-4 Common English Bible (CEB)
2 Offer a Passover sacrifice from the flock or herd to the Lord your God at the location the Lord selects for his name to reside. 3 You must not eat anything containing yeast along with it.[a] Instead, for seven days you must eat unleavened bread, bread symbolizing misery, along with it because you fled Egypt in a great hurry. Do this so you remember the day you fled Egypt for as long as you live. 4 No dough with yeast should appear in any of your territory for seven days. Furthermore, none of the meat that you sacrificed on the first night should remain until morning.
