Ezekiel 41:7-9

New Century Version

⁷ The side rooms around the Temple were wider on each higher story, so rooms were wider on the top story. A stairway went up from the lowest story to the highest through the middle story.

⁸ I also saw that the Temple had a raised base all around. Its edge was the foundation for the side rooms, and it was ten and one-half feet thick. ⁹ The outer wall of the side rooms was about nine feet thick. There was an open area between the side rooms of the Temple
