Ezekiel 41:7-9

King James Version

⁷ And there was an enlarging, and a winding about still upward to the side chambers: for the winding about of the house went still upward round about the house: therefore the breadth of the house was still upward, and so increased from the lowest chamber to the highest by the midst.

⁸ I saw also the height of the house round about: the foundations of the side chambers were a full reed of six great cubits.

⁹ The thickness of the wall, which was for the side chamber without, was five cubits: and that which was left was the place of the side chambers that were within.
