Ezekiel 41:8-12

I saw also that the house had a raised platform all around; the foundations of the side chambers were a full rod of six long cubits in height.

The thickness of the outer wall of the side chambers was five cubits. But the free space between the side chambers belonging to the temple

and the outer chambers was twenty cubits in width around the temple on every side.

The doorways of the side chambers toward the free space consisted of one doorway toward the north, and another doorway toward the south; and the width of the free space was five cubits all around.

The building that was in front of the separate area at the side toward the west was seventy cubits wide; and the wall of the building was five cubits thick all around, and its length was ninety cubits.
