1Observe the month of Abib and celebrate the Passover to the LORD your God, because in the month of Abib the LORD your God brought you out of Egypt by night.
2You are to offer to the LORD your God the Passover sacrifice from the herd or flock in the place the LORD will choose as a dwelling for His Name.
3You 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.
— Deuteronomy 16:1-3
