Numbers 18:17-19

New King James Version

^17 (A)But the firstborn of a cow, the firstborn of a sheep, or the firstborn of a goat you shall not redeem; they are holy. ^(B)You shall sprinkle their blood on the altar, and burn their fat as an offering made by fire for a sweet aroma to the Lord. ¹⁸ And their flesh shall be yours, just as the ^(C)wave^[a] breast and the right thigh are yours.

¹⁹ “All the heave offerings of the holy things, which the children of Israel offer to the Lord, I have given to you and your sons and daughters with you as an ordinance forever; ^(D)it is a covenant of salt forever before the Lord with you and your descendants with you.”
