Ezekiel 41:7-11

And the side chambers surrounding the temple were wider at each successive story. Because the structure surrounding the temple went upward by stages on all sides of the temple, for that reason the width of the temple increased as it went higher; and so one went up from the lowest story to the highest by way of the second story.

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.
