Numbers 18:9-10

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.
