Exodus 13:8–14

⁸And you shall ^ltell your son in that day, saying, ‘This is done because of what the Lord did for me when I came up from Egypt.’ ⁹It shall be as ^ma sign to you on your hand and as a memorial between your eyes, that the Lord’s law may be in your mouth; for with a strong hand the Lord has brought you out of Egypt. ¹⁰ⁿYou shall therefore keep this ³ordinance in its season from year to year.

The Law of the Firstborn

¹¹“And it shall be, when the Lord ^obrings you into the land of the ^pCanaanites, as He swore to you and your fathers, and gives it to you, ^12qthat you shall ⁴set apart to the Lord all that open the womb, that is, every firstborn that comes from an animal which you have; the males shall be the Lord’s. ¹³But ^revery firstborn of a donkey you shall redeem with a lamb; and if you will not redeem it, then you shall break its neck. And all the firstborn of man among your sons ^syou shall redeem. ^14tSo it shall be, when your son asks you in time to come, saying, ‘What is this?’ that you shall say to him, ^u‘By strength of hand the Lord brought us out of Egypt, out of the house of bondage.
