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 the first 11offspring of every womb, and 12the first offspring of every beast that you own; the males belong to the Lord. 13But 13every first 14offspring of a donkey you shall redeem with a lamb, but if you do not redeem it, then you shall break its neck; and 15every firstborn of man among your sons you shall redeem. 1416And it shall be when your son asks you in time to come, saying, ‘What is this?’ then you shall say to him, ‘17With a 18powerful hand the Lord brought us out of Egypt, from the house of 19slavery. 15It came about, when Pharaoh was stubborn about letting us go, that the 20Lord 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 21offspring of every womb, but every firstborn of my sons I redeem.’ 16So 22it shall 23serve as a sign on your hand and as 24phylacteries 25on your forehead, for with a 26powerful hand the Lord brought us out of Egypt.”
