Deuteronomy 16:1-4

NSB(i) 1 »Observe the month of Abib and celebrate the Passover to Jehovah your God. It was in the month of Abib that Jehovah your God brought you out of Egypt by night. 2 »Sacrifice the Passover to Jehovah your God from the flock and the herd, in the place where Jehovah chooses to establish his name. 3 »Do not eat leavened bread with it. Eat unleavened bread for seven days. It is the bread of affliction. You should remember all the days of your life the day when you came out of the land of Egypt in haste. 4 »No leaven should be seen with you in all your territory for seven days. None of the flesh you sacrifice on the evening of the first day shall remain overnight until morning.
