Numbers 18:7-9

Evangelical Heritage Version

⁷ But you and your sons with you will keep watch over your priesthood in connection with everything at the altar and inside the veil. You are to do this work. I am giving you your priesthood as a gift. Any unauthorized person who comes near must be put to death.

Offerings to Support the Priests and Levites

⁸ The Lord spoke to Aaron. This is what he said:

See, I myself have put you in charge of the elevated offerings made to me. All of the holy things from the Israelites I have given to you as an allotment and to your sons as a permanent right. ⁹ Part of the most holy things that are not burned in the fire will be yours. Every one of their offerings which they give to me—every one of their grain offerings, every one of their sin offerings, and every one of their restitution offerings—will be most holy for you and your sons.
