Numbers 18:9-11

9This shall be yours of the most holy things reserved from the fire: every offering of theirs, every grain offering and every sin offering and every trespass offering which they render to Me, shall be most holy for you and your sons.

10In a most holy place you shall eat it; every male shall eat it. It shall be holy to you.

11“This also is yours: the heave offering of their gift, with all the wave offerings of the children of Israel; I have given them to you, and your sons and daughters with you, as an ordinance forever. Everyone who is clean in your house may eat it.
