Numbers 18:16-18

21st Century King James Version

¹⁶ And those that are to be redeemed from a month old shalt thou redeem, according to thine estimation, for the money of five shekels, according to 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 thou shalt not redeem. They are holy. Thou shalt sprinkle their blood upon the altar, and shalt burn their fat for an offering made by fire for a sweet savor unto the Lord.

¹⁸ And the flesh of them shall be thine, as the wave breast and as the right shoulder are thine.
