Numbers 18:9-11

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 trespass-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. 11And this is thine: the heave-offering of their gift, even all the wave-offerings of the children of Israel; I have given them unto thee, and to thy sons and to thy daughters with thee, as a portion for ever; every one that is clean in thy house shall eat thereof.
