Numbers 18:15-17 And every thing that opens the womb of all flesh, whatsoever they bring to the Lord, whether man or beast, shall be thine: only the first-born of men shall be surely redeemed, and thou shalt redeem the first-born of unclean cattle.

Brenton⁽ⁱ⁾ ¹⁵ And every thing that opens the womb of all flesh, whatsoever they bring to the Lord, whether man or beast, shall be thine: only the first-born of men shall be surely redeemed, and thou shalt redeem the first-born 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 thou shalt not redeem the first-born of calves and the first-born of sheep and the first-born of goats; they are holy: and thou shalt pour their blood upon the altar, and thou shalt offer the fat as a burnt-offering for a smell of sweet savour to the Lord.
