Leviticus 6:17-23

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. 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. And Jehovah spake unto Moses, saying, This is the oblation of Aaron and of his sons, which they shall offer unto Jehovah in the day when he is anointed: the tenth part of an ephah of fine flour for a meal-offering perpetually, half of it in the morning, and half thereof in the evening. On a baking-pan it shall be made with oil; when it is soaked, thou shalt bring it in: in baken pieces shalt thou offer the meal-offering for a sweet savor unto Jehovah. And the anointed priest that shall be in his stead from among his sons shall offer it: by a statute for ever it shall be wholly burnt unto Jehovah. And every meal-offering of the priest shall be wholly burnt: it shall not be eaten.
