Ezekiel 41:9-12

9The thickness of the outer wall of the side chambers was five cubits. The free space between the side chambers of the temple and the

10other chambers was a breadth of twenty cubits all around the temple on every side.

11And the doors of the side chambers opened on the free space, one door toward the north, and another door toward the south. And the breadth of the free space was five cubits all around.

12The building that was facing the separate yard on the west side was seventy cubits broad, and the wall of the building was five cubits thick all around, and its length ninety cubits.
