Ezekiel 42:9

7And the wall that was without over against the chambers, toward the utter court on the forepart of the chambers, the length thereof was fifty cubits.

8For the length of the chambers that were in the utter court was fifty cubits: and, lo, before the temple were an hundred cubits.

9And from under these chambers was the entry on the east side, as one goeth into them from the utter court.

10The chambers were in the thickness of the wall of the court toward the east, over against the separate place, and over against 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 goings out were both according to their fashions, and according to their doors.
