Leviticus

And the remnant of the meat offering shall be Aaron’s and his sons’: it is a thing most holy of the offerings of the Lord made by fire.

And Moses spake unto Aaron, and unto Eleazar and unto Ithamar, his sons that were left, Take the meat offering that remaineth of the offerings of the Lord made by fire, and eat it without leaven beside the altar: for it is most holy:

This shall be thine of the most holy things, reserved from the fire: every oblation of theirs, every meat 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.

In the most holy place shalt thou eat it; every male shall eat it: it shall be holy unto thee.

And the remainder thereof shall Aaron and his sons eat: with unleavened bread shall it be eaten in the holy place; in the court of the tabernacle of the congregation they shall eat it.
