Numbers 18:7-9 New Century Version (NCV)
7 But only you and your sons may serve as priests. Only you may serve at the altar or go behind the curtain. I am giving you this gift of serving as a priest, and anyone else who comes near the Holy Place will be put to death.”
8 Then the Lord said to Aaron, “I myself make you responsible for the offerings given to me. All the holy offerings that the Israelites give to me, I give to you and your sons as your share, your continual portion. 9 Your share of the holy offerings is that part which is not burned. When the people bring me gifts as most holy offerings, whether they are grain or sin or penalty offerings, they will be set apart for you and your sons.

7 But only you and your sons may serve as priests in connection with everything at the altar and inside the curtain. I am giving you the service of the priesthood as a gift. Anyone else who comes near the sanctuary is to be put to death.”
Offerings for Priests and Levites
8 Then the Lord said to Aaron, “I myself have put you in charge of the offerings presented to me; all the holy offerings the Israelites give me I give to you and your sons as your portion, your perpetual share. 9 You are to have the part of the most holy offerings that is kept from the fire. From all the gifts they bring me as most holy offerings, whether grain or sin[a] or guilt offerings, that part belongs to you and your sons.
