9 It shall be as a sign to you on your hand and as a memorial on your forehead, in order that the Lord’s law may be in your mouth. For with a strong hand the Lord brought you out of Egypt.
10 You shall, therefore, keep this ordinance at its appointed time from year to year.
11 “It shall be when the Lord brings you into the land of the Canaanites, just as He swore to you and to your fathers, and shall give it you,
12 that you shall set apart to the Lord the first offspring of every womb and the first offspring of every beast which you have. The males shall be the Lord’s.
13 But every first offspring of a donkey you shall redeem with a lamb. And if you do not redeem it, then you shall break its neck, and all the firstborn of man among your sons you shall redeem.
14 “It shall be when your son asks you in time to come, saying, ‘What is this?’ that you shall say to him, ‘With a strong hand the Lord brought us out from Egypt, from the house of bondage.
15 And when Pharaoh stubbornly refused to let us go, that the Lord killed all the firstborn in the land of Egypt, both the firstborn of man, and the firstborn of beast. Therefore, I sacrifice to the Lord the first male offspring of every womb, but all the firstborn of my sons I redeem.’
