Numbers 18:5-13

“Your job is to take care of the Sanctuary and the Altar so that there will be no more outbreaks of anger on the People of Israel. I personally have picked your brothers, the Levites, from Israel as a whole. I’m giving them to you as a gift, a gift of GOD, to help with the work of the Tent of Meeting. But only you and your sons may serve as priests, working around the Altar and inside the curtain. The work of the priesthood is my exclusive gift to you; it cannot be delegated—anyone else who invades the Sanctuary will be executed.” 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. “You also get the Wave-Offerings from the People of Israel. I present them to you and your sons and daughters as a gift. This is the standing rule. Anyone in your household who is ritually clean may eat it. I also give you all the best olive oil, the best new wine, and the grain that is offered to GOD as the firstfruits of their harvest—all the firstfruits they offer to GOD are yours. Anyone in your household who is ritually clean may eat it.
