Exodus 13:11-16

11“Now when 1the Lord brings you to the land of the Canaanite, as 2He swore to you and to your fathers, and gives it to you, 123you shall 4devote 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 5every firstborn of a donkey you shall redeem with a lamb, but if you do not redeem it, then you shall break its neck; and 6every 7firstborn among your sons you shall redeem. 148And it shall be when your son asks you in time to come, saying, ‘What is this?’ then you shall say to him, ‘9With 10a powerful hand the Lord brought us out of Egypt, from the house of 11slavery. 15And it came about, when Pharaoh was stubborn about letting us go, that the 12Lord 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 13it shall 14serve as a sign on your hand and as 15phylacteries 16on your forehead, for with 17a powerful hand the Lord brought us out of Egypt.”
