Ezekiel 46:19-20

Then 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. And 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 meal-offering; that they bring them not forth into the outer court, to sanctify the people.
