Ezekiel 42:8-12

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

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

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

And 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.

And 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.
