Exodus 13:11–16
11 “Now when athe Lord brings you to the land of the Canaanite, as bHe swore to you and to your fathers, and gives it to you,
12 ayou shall 1devote to the Lord the first 2offspring of every womb, and 3the first offspring of every beast that you own; the males belong to the Lord.
13 “But aevery first 1offspring of a donkey you shall redeem with a lamb, but if you do not redeem it, then you shall break its neck; and bevery firstborn of man among your sons you shall redeem.
14 “aAnd it shall be when your son asks you in time to come, saying, ‘What is this?’ then you shall say to him, ‘bWith a 1powerful hand the Lord brought us out of Egypt, from the house of 2slavery.
15 ‘It came about, when Pharaoh was stubborn about letting us go, that the aLord 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 1offspring of every womb, but every firstborn of my sons I redeem.’
16 “So ait shall 1serve as a sign on your hand and as 2phylacteries 3on your forehead, for with a 4powerful hand the Lord brought us out of Egypt.”
