Numbers 18:17-19

New International Version - UK

¹⁷ ‘But you must not redeem the firstborn of an ox, a sheep or a goat; they are holy. Splash their blood against the altar and burn their fat as a food offering, an aroma pleasing to the Lord. ¹⁸ Their meat is to be yours, just as the breast of the wave offering and the right thigh are yours. ¹⁹ Whatever is set aside from the holy offerings the Israelites present to the Lord I give to you and your sons and daughters as your perpetual share. It is an everlasting covenant of salt before the Lord for both you and your offspring.’
