Leviticus 6:14-16, 26

“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.

The priest who offers it for sin shall eat it. In a holy place it shall be eaten, in the court of the tent of meeting.
