Exodus 13:2-12

2“Sanctify to Me [that is, set apart for My purpose] every firstborn, the first offspring of every womb among the children of Israel, both of man and of animal; it is Mine.”

3Moses said to the people, “Remember [solemnly observe and commemorate] this day on which you came out of Egypt, out of the house of bondage and slavery; for by a strong and powerful hand the Lord brought you out of this place. And nothing leavened shall be eaten.

4On this day in the month Abib, you are about to go onward.

5And it shall be when the Lord brings you into the land of the Canaanite, the Hittite, the Amorite, the Hivite, and the Jebusite, which He swore to your fathers to give you, a land [of abundance] flowing with milk and honey, that you shall keep and observe this rite (service) in this month.

6For seven days you shall eat unleavened bread, and on the seventh day there shall be a feast to the Lord.

7Unleavened bread shall be eaten throughout the seven days; no leavened bread shall be seen with you, nor shall there be leaven within the borders of your territory.

8You shall explain this to your son on that day, saying, ‘It is because of what the Lord did for me when I came out of Egypt.’

9It shall serve as a sign to you on your hand (arm), and as a reminder on your forehead, so that the instruction (law) of the Lord may be in your mouth; for with a strong and powerful hand the Lord brought you out of Egypt.

10Therefore, you shall keep this ordinance at this time from year to year.

11“Now it shall be when the Lord brings you into the land of the Canaanite, as He swore to you and your fathers, and gives it to you,

12you shall set apart and dedicate to the Lord all that first opens the womb. All the firstborn males of your livestock shall be the Lord’s.
