Numbers 18:9-11

9This shall be yours from the most holy gifts reserved from the fire; every offering of theirs, even 1every grain offering and every 2sin offering and every guilt offering, which they shall render 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.

11This also is yours, 3the offering of their gift, even all the wave offerings of the sons of Israel; I have 4given them to you and to your sons and daughters with you as a perpetual allotment. Everyone of your household who is clean may eat it.
