Deuteronomy 16:3-4 You must not eat leavened bread with it; for seven days you are to eat with it unleavened bread, the bread of affliction, because you left the land of Egypt in haste—so that you may remember for the rest of your life the day you left the land of Egypt.

MSB⁽ⁱ⁾ ³ You must not eat leavened bread with it; for seven days you are to eat with it unleavened bread, the bread of affliction, because you left the land of Egypt in haste—so that you may remember for the rest of your life the day you left the land of Egypt. ⁴ No leaven is to be found in all your land for seven days, and none of the meat you sacrifice in the evening of the first day shall remain until morning.
