Numbers 18:15-17

English Standard Version

^15 (A)Everything that opens the womb of all flesh, whether man or beast, which they offer to the Lord, shall be yours. Nevertheless, ^(B)the firstborn of man you shall redeem, and the firstborn of unclean animals you shall redeem. ¹⁶ And their redemption price ^(C)(at a month old you shall redeem them) you shall fix at five shekels^[a] in silver, according to the shekel of the sanctuary, ^(D)which is twenty gerahs. ^17 (E)But the firstborn of a cow, or the firstborn of a sheep, or the firstborn of a goat, you shall not redeem; they are holy. You shall sprinkle their blood on the altar and shall burn their fat as a food offering, with a pleasing aroma to the Lord.
