Numbers 18:16-18

English Standard Version

¹⁶ And their redemption price ^(A)(at a month old you shall redeem them) you shall fix at five shekels^[a] in silver, according to the shekel of the sanctuary, ^(B)which is twenty gerahs. ^17 (C)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. ¹⁸ But their flesh shall be yours, as ^(D)the breast that is waved and as the right thigh are yours.
