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