Ezekiel 41:5-7 Common English Bible (CEB)

5. When he measured the wall of the temple, it was nine feet, and the side chambers that went all the way around the temple were six feet.

6. Now these side chambers adjoined each other, thirty chambers in three stories. The side chambers had a ledge in the temple wall all the way around to serve as supports, but these supports were not inserted into the temple wall itself.

7. A wide ramp ascended stage by stage to the side chambers all the way around the temple. In this way, the ascent stage by stage all around the temple added to the temple’s width. One ascended from the foundation to the top by way of the middle story.
