All the descendants of Jacob were seventy people; Joseph was [already] in Egypt.

“Sanctify to Me every firstborn, the first offspring of every womb among the sons of Israel, both of man and beast; it belongs to Me.”

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.

But every first offspring of a donkey you shall redeem with a lamb, but if you do not redeem it, then you shall break its neck; and every firstborn of man among your sons you shall redeem.

It came about, when Pharaoh was stubborn about letting us go, that the Lord 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 offspring of every womb, but every firstborn of my sons I redeem.’

And they will be on Aaron and on his sons when they come to the tent of assembly or when they approach the altar to serve in the sanctuary, so that they will not bear guilt and die. [It is] a lasting statute for him and for his offspring after him.

And they will wash their hands and their feet so that they do not die, and it will be a lasting rule for them--to him and to his offspring throughout their generations.

Remember Your servants Abraham, Isaac, and Israel—You swore to them by Your very self and declared, ‘I will make your offspring as numerous as the stars of the sky and will give your offspring all this land that I have promised, and they will inherit it forever.’”

The Lord spoke to Moses: “Go, leave here, you and the people you brought up from the land of Egypt, to the land I promised to Abraham, Isaac, and Jacob, saying: I will give it to your offspring.

“The first offspring from every womb belongs to Me, and all your male livestock, the first offspring from cattle and sheep.

You shall redeem with a lamb the first offspring from a donkey; and if you do not redeem it, then you shall break its neck. You shall redeem all the firstborn of your sons. None shall appear before Me empty-handed.
