Ezekiel 46:19-20

19After he brought me through the entry, which was at the side of the gate, into the holy chambers of the priests, which looked toward the north: and, behold, there was a place on the two sides westward. 20Then 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 grain offering; that they bear them not out into the utter court, to sanctify the people.
