Exodus 13:1-16

And Jehovah spake unto Moses, saying, Sanctify unto me all the first-born, whatsoever openeth the womb among the children of Israel, both of man and of beast: it is mine. And 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 Jehovah brought you out from this place: there shall no leavened bread be eaten. This day ye go forth in the month Abib. And it shall be, when Jehovah 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. Seven days thou shalt eat unleavened bread, and in the seventh day shall be a feast to Jehovah. Unleavened 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. And thou shalt tell thy son in that day, saying, It is because of that which Jehovah did for me when I came forth out of Egypt. And it shall be for a sign unto thee upon thy hand, and for a memorial between thine eyes, that the law of Jehovah may be in thy mouth: for with a strong hand hath Jehovah brought thee out of Egypt. Thou shalt therefore keep this ordinance in its season from year to year. And it shall be, when Jehovah shall bring thee into the land of the Canaanite, as he sware unto thee and to thy fathers, and shall give it thee, that thou shalt set apart unto Jehovah all that openeth the womb, and every firstling which thou hast that cometh of a beast; the males shall be Jehovah’s. And every firstling of an ass thou shalt redeem with a lamb; and if thou wilt not redeem it, then thou shalt break its neck: and all the first-born of man among thy sons shalt thou redeem. And it shall be, when thy son asketh thee in time to come, saying, What is this? that thou shalt say unto him, By strength of hand Jehovah brought us out from Egypt, from the house of bondage: and it came to pass, when Pharaoh would hardly let us go, that Jehovah slew all the first-born in the land of Egypt, both the first-born of man, and the first-born of beast: therefore I sacrifice to Jehovah all that openeth the womb, being males; but all the first-born of my sons I redeem. And it shall be for a sign upon thy hand, and for frontlets between thine eyes: for by strength of hand Jehovah brought us forth out of Egypt.
