Numbers 18:15-17 Every thing that opens the womb in all flesh, which they bring to the LORD, whether it be of men or beasts, shall be yours: Nevertheless the firstborn of man shall you surely redeem, and the firstling of unclean beasts shall you redeem.

TKJU⁽ⁱ⁾ ¹⁵ Every thing that opens the womb in all flesh, which they bring to the LORD, whether it be of men or beasts, shall be yours: Nevertheless the firstborn of man shall you surely redeem, and the firstling of unclean beasts shall you redeem. ¹⁶ And those that are to be redeemed from a month old shall you redeem, according to your estimation, for the money of five shekels, after the shekel of the sanctuary, which is twenty gerahs. ¹⁷ But the firstling of a cow, or the firstling of a sheep, or the firstling of a goat, you shall not redeem; they are holy: You shall sprinkle their blood on the altar, and shall burn their fat for an offering made by fire, for a sweet smell to the LORD.
