Exodus 13:12–15

you shall set apart to the Lord all that first opens the womb. All the firstborn of your animals that are males shall be the Lord’s. Every firstborn of a donkey you shall redeem with a lamb, or if you will not redeem it you shall break its neck. Every firstborn of man among your sons you shall redeem. And when in time to come your son asks you, ‘What does this mean?’ you shall say to him, ‘By a strong hand the Lord brought us out of Egypt, from the house of slavery. For when Pharaoh stubbornly refused to let us go, the Lord killed all the firstborn in the land of Egypt, both the firstborn of man and the firstborn of animals. Therefore I sacrifice to the Lord all the males that first open the womb, but all the firstborn of my sons I redeem.’

you are to give over to the Lord the first offspring of every womb. All the firstborn males of your livestock belong to the Lord. Redeem with a lamb every firstborn donkey, but if you do not redeem it, break its neck. Redeem every firstborn among your sons.

“In days to come, when your son asks you, ‘What does this mean?’ say to him, ‘With a mighty hand the Lord brought us out of Egypt, out of the land of slavery. When Pharaoh stubbornly refused to let us go, the Lord killed the firstborn of both people and animals in Egypt. This is why I sacrifice to the Lord the first male offspring of every womb and redeem each of my firstborn sons.’

you are to present to the Lord every firstborn male of the womb. All firstborn offspring of the livestock you own that are males will be the Lord’s. You must redeem every firstborn of a donkey with a flock animal, but if you do not redeem it, break its neck. However, you must redeem every firstborn among your sons.

“In the future, when your son asks you, ‘What does this mean?’ say to him, ‘By the strength of his hand the Lord brought us out of Egypt, out of the place of slavery. When Pharaoh stubbornly refused to let us go, the Lord killed every firstborn male in the land of Egypt, both the firstborn of humans and the firstborn of livestock. That is why I sacrifice to the Lord all the firstborn of the womb that are males, but I redeem all the firstborn of my sons.’

you must present all firstborn sons and firstborn male animals to the Lord, for they belong to him. A firstborn donkey may be bought back from the Lord by presenting a lamb or young goat in its place. But if you do not buy it back, you must break its neck. However, you must buy back every firstborn son.

“And in the future, your children will ask you, ‘What does all this mean?’ Then you will tell them, ‘With the power of his mighty hand, the Lord brought us out of Egypt, the place of our slavery. Pharaoh stubbornly refused to let us go, so the Lord killed all the firstborn males throughout the land of Egypt, both people and animals. That is why I now sacrifice all the firstborn males to the Lord—except that the firstborn sons are always bought back.’

That thou shalt set apart unto the Lord all that openeth the matrix, and every firstling that cometh of a beast which thou hast; the males shall be the Lord’s. And every firstling of an ass thou shalt redeem with a lamb; and if thou wilt not redeem it, then thou shalt break his neck: and all the firstborn of man among thy children shalt thou redeem. And it shall be when thy son asketh thee in time to come, saying, What is this? that thou shalt say unto him, By strength of hand the Lord brought us out from Egypt, from the house of bondage: And it came to pass, when Pharaoh would hardly let us go, that the Lord slew all the firstborn in the land of Egypt, both the firstborn of man, and the firstborn of beast: therefore I sacrifice to the Lord all that openeth the matrix, being males; but all the firstborn of my children I redeem.
