Ezekiel 46:19-20

19Then he brought me through the passage which was at the side of the gate, into the holy cells which were for the priests, which looked toward the north; and behold, a place was there at the end westward.

20And he said unto me, This is the place where the priests shall boil the trespass-offering, and the sin-offering, [and] where they shall bake the oblation, that they bring them not out into the outer court, so as to hallow the people.
