Ezekiel 41:8-11

8I also saw an elevation all around the temple; it was the foundation of the side chambers, a full rod, that is, six cubits high.

9The thickness of the outer wall of the side chambers was five cubits, and so also the remaining terrace by the place of the side chambers of the temple.

10And between it and the wall chambers was a width of twenty cubits all around the temple on every side.

11The doors of the side chambers opened on the terrace, one door toward the north and another toward the south; and the width of the terrace was five cubits all around.
