Ezekiel 41:8-11

8I saw also that the temple had a raised platform all around; the foundations of the side chambers measured a full reed of six long cubits.

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.
