Numbers 18:8-10

8And the LORD spake unto Aaron, And I, behold, I have given thee the charge of mine heave offerings, even all the hallowed things of the children of Israel, unto thee have I given them by reason of the anointing, and to thy sons, as a due for ever.

9This shall be thine of the most holy things, reserved from the fire: every oblation of theirs, even every meal offering of theirs, and every sin offering of theirs, and every guilt offering of theirs, which they shall render unto me, shall be most holy for thee and for thy sons.

10As the most holy things shalt thou eat thereof: every male shall eat thereof; it shall be holy unto thee.
