Leviticus 6:16, 18, 20, 26

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.

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.”

“This is the offering that Aaron and his sons shall offer to the LORD on the day when he is anointed: a tenth of an ephah of fine flour as a regular grain offering, half of it in the morning and half in the evening.

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.
