Ezekiel 41:8 in the King James Version
I saw also the height of the house round about: the foundations of the side chambers were a full reed of six great cubits.
Context
7 The 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.
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.
