Exodus 13:2-10

2Sanctify unto me all the firstborn, whatsoever openeth the womb among the children of Israel, both of man and of beast: it is mine.

3And Moses said unto the people, Remember this day, in which ye came out from Egypt, out of the house of bondage; for by strength of hand the LORD brought you out from this place: there shall no leavened bread be eaten.

4This day ye go forth in the month Abib.

5And it shall be when the LORD shall bring thee into the land of the Canaanite, and the Hittite, and the Amorite, and the Hivite, and the Jebusite, which he sware unto thy fathers to give thee, a land flowing with milk and honey, that thou shalt keep this service in this month.

6Seven days thou shalt eat unleavened bread, and in the seventh day shall be a feast to the LORD.

7Unleavened bread shall be eaten throughout the seven days; and there shall no leavened bread be seen with thee, neither shall there be leaven seen with thee, in all thy borders.

8And thou shalt tell thy son in that day, saying, It is because of that which the LORD did for me when I came forth out of Egypt.

9And it shall be for a sign unto thee upon thine hand, and for a memorial between thine eyes, that the law of the LORD may be in thy mouth: for with a strong hand hath the LORD brought thee out of Egypt.

10Thou shalt therefore keep this ordinance in its season from year to year.
