Ezekiel 42:7-12

7An outer wall in front of the chambers was fifty cubits long and ran parallel to the chambers and the outer court. 8For the chambers on the outer court were fifty cubits long, while those facing the temple were a hundred cubits long. 9And below these chambers was the entrance on the east side as one enters them from the outer court.

10On the south side1 along the length of the wall of the outer court were chambers adjoining the courtyard and opposite the building, 11with a passageway in front of them, just like the chambers that were on the north. They had the same length and width, with similar exits and dimensions. 12And corresponding to the doors of the chambers that were facing south, there was a door in front of the walkway that was parallel to the wall extending eastward.
