Ezekiel 41:8

6The side rooms were in three stories, one over another, and thirty in each story. They entered into the wall which belonged to the house for the side rooms all around, that they might be supported and not penetrate the wall of the house.

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.
