TSK · Numbers 18:15

"Sanctify to me all of the firstborn, whatever opens the womb among the children of Israel, both of man and of animal. It is mine."

Every firstborn of a donkey you shall redeem with a lamb; and if you will not redeem it, then you shall break its neck; and you shall redeem all the firstborn of man among your sons.

"You shall not delay to offer from your harvest and from the outflow of your presses. "You shall give the firstborn of your sons to me.

"'Only the firstborn among animals, which is made a firstborn to Yahweh, no man may dedicate it; whether an ox or sheep, it is Yahweh's.

For the redemption of the two hundred seventy-three of the firstborn of the children of Israel, who exceed the number of the Levites,

let the priests take it to them, every man from his acquaintance; and they shall repair the breaches of the house, wherever any breach shall be found."
