Numbers 18:7-9 Tree of Life Version (TLV)
7 But you and your sons with you are to maintain your priesthood for everything pertaining to the altar and inside the parokhet. I am giving you the ministry of the priesthood as a gift. Anyone unauthorized who approaches will die.”
8 Adonai then said to Aaron, “See, I have given you charge over all My offerings. All the sacred things from Bnei-Yisrael I have given to you as set aside for you and your sons as a permanent share. 9 You are to have the part of the most holy things that is kept from the fire. Whether grain, sin or guilt offerings that they bring to Me as most holy—they are for you and your sons.
