Exodus 13:2-10

2“Consecrate to Me all the firstborn, whatever opens the womb among the children of Israel, both of man and beast; it is Mine.”

3And Moses said to the people: “Remember this day in which you went out of Egypt, out of the house of bondage; for by strength of hand the Lord brought you out of this place. No leavened bread shall be eaten.

4On this day you are going out, in the month Abib.

5And it shall be, when the Lord brings you into the land of the Canaanites and the Hittites and the Amorites and the Hivites and the Jebusites, which He swore to your fathers to give you, a land flowing with milk and honey, that you shall keep this service in this month.

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

7Unleavened bread shall be eaten seven days. And no leavened bread shall be seen among you, nor shall leaven be seen among you in all your quarters.

8And you shall tell your son in that day, saying, ‘This is done because of what the Lord did for me when I came up from Egypt.’

9It shall be as a sign to you on your hand and as a memorial between your eyes, that the Lord’s law may be in your mouth; for with a strong hand the Lord has brought you out of Egypt.

10You shall therefore keep this ordinance in its season from year to year.
