Numbers 18:8-10, 17-19

GOD spoke to Aaron, “I am personally putting you in charge of my contributions, all the holy gifts I get from the People of Israel. I am turning them over to you and your children for your personal use. This is the standing rule. You and your sons get what’s left from the offerings, whatever hasn’t been totally burned up on the Altar—the leftovers from Grain-Offerings, Absolution-Offerings, and Compensation-Offerings. Eat it reverently; it is most holy; every male may eat it. Treat it as holy.

“On the other hand, you don’t redeem a firstborn ox, sheep, or goat—they are holy. Instead splash their blood on the Altar and burn their fat as a Fire-Gift, a pleasing fragrance to GOD. But you get the meat, just as you get the breast from the Wave-Offering and the right thigh. All the holy offerings that the People of Israel set aside for GOD, I’m turning over to you and your children. That’s the standard rule and includes both you and your children—a Covenant-of-Salt, eternal and unchangeable before GOD.”
