Albert Barnes Commentary Leviticus 6:14-18

"And this is the law of the meal-offering: the sons of Aaron shall offer it before Jehovah, before the altar. And he shall take up therefrom his handful, of the fine flour of the meal-offering, and of the oil thereof, and all the frankincense which is upon the meal-offering, and shall burn it upon the altar for a sweet savor, as the memorial thereof, unto Jehovah. 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. 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." — Leviticus 6:14-18 (ASV)

See Leviticus 2:1-10; Exodus 29:40–41.
