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

CAB⁽ⁱ⁾ ¹⁵ And everything that opens the womb of all flesh, whatsoever they bring to the Lord, whether man or beast, shall be yours: 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 gerahs 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 an aroma of sweet savor to the Lord.
