Numbers 18:15-17 And every thing that opens the womb of all flesh, whatever they bring to the Lord, whether man or beast, shall be your: only the firstborn of men shall be surely redeemed, and you shall redeem the firstborn of unclean cattle.

LXX2012⁽ⁱ⁾ ¹⁵ And every thing that opens the womb of all flesh, whatever they bring to the Lord, whether man or beast, shall be your: only the firstborn of men shall be surely redeemed, and you shall redeem the firstborn of unclean cattle. ¹⁶ And the redemption of them [shall be] from a month old; their valuation of five shekels—it is twenty oboli according to the holy shekel. ¹⁷ But you shall not redeem the firstborn of calves and the firstborn of sheep and the firstborn of goats; they are holy: and you shall pour their blood upon the altar, and you shall offer the fat as a burnt offering for a smell of sweet savor to the Lord.
