Numbers 18:8-10

8Then the Lord spoke to Aaron, “Now behold, I Myself have put you in charge of My 12offerings, all the holy gifts of the sons of Israel I have given to you as a portion and to your sons as a permanent allotment.

9This shall be yours from the most holy gifts reserved from the fire; every offering of theirs, namely 3every grain offering, every 4sin offering, and every guilt offering, with which they shall make restitution to Me, shall be most holy for you and for your sons.

10As the most holy gifts you shall eat it; every male shall eat it. It shall be holy to you.
