Numbers 18:17-19

International Standard Version

¹⁷ But you are not to redeem the firstborn of a cow, sheep, or a female goat. They are holy. You are to sprinkle their blood on the altar and burn their fat for an offering made by fire, a pleasing aroma to the Lord. ¹⁸ Their meat is to belong to you, just as the breast wave offering and the right thigh is yours. ¹⁹ I’m giving you, your sons, and your daughters as a prescribed portion forever all the raised offerings of the consecrated things that the Israelis offer to the Lord. It’s a salt covenant forever before the Lord with you and your descendants with you.”
