Ezekiel 42:10-12

10The chambers were in the thickness of the wall of the court toward the east, opposite the separate place, and opposite the building.

11And the way before them was like the appearance of the chambers which were toward the north, as long as they, and as broad as they: and all their exits were both according to their fashions, and according to their doors.

12And according to the doors of the chambers that were toward the south was a door in the head of the way, even the way directly before the wall toward the east, as one entereth into them.
