Leviticus 6:14-16, 26

‘This is the law of the grain offering: The sons of Aaron shall offer it on the altar before the LORD. He shall take from it his handful of the fine flour of the grain offering, with its oil, and all the frankincense which is on the grain offering, and shall burn it on the altar for a sweet aroma, as a memorial to the LORD. And the remainder of it Aaron and his sons shall eat; with unleavened bread it shall be eaten in a holy place; in the court of the tabernacle 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 tabernacle of meeting.
