Leviticus 6:26

Then said he unto me, This is the place where the priests shall boil the trespass offering and the sin offering, where they shall bake the meat offering; that they bear them not out into the utter court, to sanctify the people.

Then said he unto me, The north chambers and the south chambers, which are before the separate place, they be holy chambers, where the priests that approach unto the LORD shall eat the most holy things: there shall they lay the most holy things, and the meat offering, and the sin offering, and the trespass offering; for the place is holy.

They eat up the sin of my people, and they set their heart on their iniquity.

And he reared up the court round about the tabernacle and the altar, and set up the hanging of the court gate. So Moses finished the work.

And the remainder thereof shall Aaron and his sons eat: with unleavened bread shall it be eaten in the holy place; in the court of the tabernacle of the congregation they shall eat it.
