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 the first 5offspring of every womb, and 6the first offspring of every beast that you own; the males belong to the Lord. 13But 7every first 8offspring of a donkey you shall redeem with a lamb, but if you do not redeem it, then you shall break its neck; and 9every firstborn of man among your sons you shall redeem. 1410And it shall be when your son asks you in time to come, saying, ‘What is this?’ then you shall say to him, ‘11With a 12powerful hand the Lord brought us out of Egypt, from the house of 13slavery. 15It came about, when Pharaoh was stubborn about letting us go, that the 14Lord killed every firstborn in the land of Egypt, both the firstborn of man and the firstborn of beast. Therefore, I sacrifice to the Lord the males, the first 15offspring of every womb, but every firstborn of my sons I redeem.’ 16So 16it shall 17serve as a sign on your hand and as 18phylacteries 19on your forehead, for with a 20powerful hand the Lord brought us out of Egypt.”
