Leviticus 6:14-18

“And this is the law of the grain offering. The sons of Aaron shall offer it before the LORD in front of the altar. And one shall take from it a handful of the fine flour of the grain offering and its oil and all the frankincense that is on the grain offering and burn this as its memorial portion on the altar, a pleasing aroma to the LORD. And the rest of it Aaron and his sons shall eat. It shall be eaten unleavened in a holy place. In the court of the tent of meeting they shall eat it. It shall not be baked with leaven. I have given it as their portion of my food offerings. It is a thing most holy, like the sin offering and the guilt offering. Every male among the children of Aaron may eat of it, as decreed forever throughout your generations, from the LORD’s food offerings. Whatever touches them shall become holy.”
