Numbers 18:8-10

8The Lord said to Aaron, “I am putting you in charge of all the contributions given to me. I am giving you and your descendants all the holy gifts from the Israelites as your share. These contributions will always be yours.

9That part of the most holy offerings which is not burned belongs to you. It may come from a grain offering, an offering for sin, or a guilt offering. Whatever is brought to me as a most holy offering will belong to you and your sons.

10Eat it in a most holy place. Any male may eat it. You must consider it holy.
