Everything that opens the womb in all flesh, which they bring to Jehovah, of men or animals, shall be yours. Nevertheless, the first-born of man you shall surely redeem, and the first-born of unclean animals you shall redeem.

And those that are to be redeemed from a month old you shall redeem, according to your judgment for the silver of five shekels, according to the shekel of the sanctuary, which is twenty gerahs.

But the first-born of a cow, or the first-born of a sheep, or the first-born of a goat, you shall not redeem. They are holy. You shall sprinkle their blood upon the altar, and shall burn their fat, an offering made by fire, for a sweet savor to Jehovah.
