Numbers 18:7-9

New Living Translation

⁷ But you and your sons, the priests, must personally handle all the priestly rituals associated with the altar and with everything behind the inner curtain. I am giving you the priesthood as your special privilege of service. Any unauthorized person who comes too near the sanctuary will be put to death.”

⁸ The Lord gave these further instructions to Aaron: “I myself have put you in charge of all the holy offerings that are brought to me by the people of Israel. I have given all these consecrated offerings to you and your sons as your permanent share. ⁹ You are allotted the portion of the most holy offerings that is not burned on the fire. This portion of all the most holy offerings—including the grain offerings, sin offerings, and guilt offerings—will be most holy, and it belongs to you and your sons.
