Numbers 18:8

Then the Lord spoke to Aaron , Behold, I have given you charge of the contributions made to me, all the consecrated things of the people of Israel . I have given them to you as a portion and to your sons as a perpetual due .

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.

And the Lord spake unto Aaron, Behold, I also have given thee the charge of mine heave offerings of all the hallowed things of the children of Israel; unto thee have I given them by reason of the anointing, and to thy sons, by an ordinance for ever.
