Leviticus 6
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.
