Ezekiel 46:19-20

19Then he brought me through the entry, which was at the side of the gate, into the holy chambers for the priests, which looked toward the north: and behold, there was a place on the hinder part westward.

20And he said unto me, This is the place where the priests shall boil the guilt offering and the sin offering, where they shall bake the meal offering; that they bring them not forth into the outer court, to sanctify the people.
