Ezekiel 41:9

7The side rooms were wider on the higher levels, because the walls were narrower at the higher levels. Therefore the width of the house increased upward; and so one went up from the lowest level to the highest through the middle level.

8I saw also that the house had a raised base all around. The foundations of the side rooms were a full reed of six great cubits.

9The thickness of the outer wall of the side rooms was five cubits. That which was left was the place of the side rooms that belonged to the house.

10Between the rooms was a width of twenty cubits around the house on every side.

11The doors of the side rooms were toward an open area that was left, one door toward the north, and another door toward the south. The width of the open area was five cubits all around.
