Leviticus 6:16-18

16And the remainder of it Aaron and his sons shall eat; with unleavened bread it shall be eaten in a holy place; in the court of the tabernacle of meeting they shall eat it.

17It shall not be baked with leaven. I have given it as their portion of My offerings made by fire; it is most holy, like the sin offering and the trespass offering.

18All the males among the children of Aaron may eat it. It shall be a statute forever in your generations concerning the offerings made by fire to the Lord. Everyone who touches them must be holy.’ ”
