Leviticus 6
16 Ref And that which is left thereof shall Aaron and his sons eat: it shall be eaten without leaven in a holy place; in the court of the tent of meeting they shall eat it.
17 Ref It shall not be baken with leaven. I have given it as their portion of my offerings made by fire; it is most holy, as the sin-offering, and as the trespass-offering.
18 Ref Every male among the children of Aaron shall eat of it, as `his' portion for ever throughout your generations, from the offerings of Jehovah made by fire: whosoever toucheth them shall be holy.
