Leviticus 6:16-18

King James Version

¹⁶ 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.

¹⁷ It shall not be baken with leaven. I have given it unto them for their portion of my offerings made by fire; it is most holy, as is the sin offering, and as the trespass offering.

¹⁸ All the males among the children of Aaron shall eat of it. It shall be a statute for ever in your generations concerning the offerings of the Lord made by fire: every one that toucheth them shall be holy.
