Exodus 13:4

¹⁸“You shall keep the feast of unleavened bread. Seven days you shall eat unleavened bread, as I commanded you, at the time appointed in the month Abib; for in the month Abib you came out of Egypt.

¹⁵You shall observe the feast of unleavened bread. Seven days you shall eat unleavened bread, as I commanded you, at the time appointed in the month Abib (for in it you came out of Egypt), and no one shall appear before me empty.

²“This month shall be to you the beginning of months. It shall be the first month of the year to you.

¹Observe the month of Abib, and keep the Passover to the LORD your God; for in the month of Abib the LORD your God brought you out of Egypt by night. ²You shall sacrifice the Passover to the LORD your God, of the flock and the herd, in the place which the LORD shall choose to cause his name to dwell there. ³You shall eat no leavened bread with it. You shall eat unleavened bread with it seven days, even the bread of affliction (for you came out of the land of Egypt in haste) that you may remember the day when you came out of the land of Egypt all the days of your life.
