Deuteronomy 16:2-4

New American Standard Bible

² You shall sacrifice the Passover to the Lord your God from the flock and the herd, in the place where the Lord chooses to establish His name. ^3 (A)You shall not eat leavened bread with it; for seven days you shall eat unleavened bread with it, the bread of affliction (for you came out of the land of Egypt in a hurry), so that you will remember the day when you came out of the land of Egypt ^(B)all the days of your life. ⁴ For seven days no leaven shall be seen with you in your entire territory, and ^(C)none of the meat which you sacrifice on the evening of the first day shall be left overnight until the morning.
