Exodus 13:9-16

9And 1it shall 2serve as a sign to you on your hand, and as a reminder 3on your forehead, that the law of the Lord may be in your mouth; for with 4a powerful hand the Lord brought you out of Egypt. 10Therefore, you shall 5keep this ordinance at its appointed time from 6year to year.

11“Now when 7the Lord brings you to the land of the Canaanite, as 8He swore to you and to your fathers, and gives it to you, 129you shall 10devote to the Lord every firstborn of a womb, and every firstborn offspring of an animal that you own; the males belong to the Lord. 13But 11every firstborn of a donkey you shall redeem with a lamb, but if you do not redeem it, then you shall break its neck; and 12every 13firstborn among your sons you shall redeem. 1414And it shall be when your son asks you in time to come, saying, ‘What is this?’ then you shall say to him, ‘15With 16a powerful hand the Lord brought us out of Egypt, from the house of 17slavery. 15And it came about, when Pharaoh was stubborn about letting us go, that the 18Lord put to death every firstborn in the land of Egypt, from human firstborns to animal firstborns. Therefore, I sacrifice to the Lord the males, every firstborn of a womb, but every firstborn of my sons I redeem.’ 16So 19it shall 20serve as a sign on your hand and as 21phylacteries 22on your forehead, for with 23a powerful hand the Lord brought us out of Egypt.”
