Leviticus 6:14-16, 26

‘Now this is the law of the grain offering: the sons of Aaron shall present it before the LORD in front of the altar. Then one of them shall lift up from it a handful of the fine flour of the grain offering, with its oil and all the incense that is on the grain offering, and he shall offer it up in smoke on the altar, a soothing aroma, as its memorial offering to the LORD. What is left of it Aaron and his sons are to eat. It shall be eaten as unleavened cakes in a holy place; they are to eat it in the court of the tent of meeting.

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