Ezekiel 41:6–11

⁶And the side chambers were in three stories, one over another, thirty in each story. There were offsets all around the wall of the temple to serve as supports for the side chambers, so that they should not be supported by the wall of the temple. ⁷And the side chambers became broader as they rose from story to story, corresponding to the enlargement of the offset from story to story round about the temple; on the side of the temple a stairway led upward, and thus one went up from the lowest story to the top story through the middle story. ⁸I saw also that the temple had a raised platform round about; the foundations of the side chambers measured a full reed of six long cubits. ⁹The thickness of the outer wall of the side chambers was five cubits; and the part of the platform which was left free was five cubits. Between the platform of the temple and the ¹⁰chambers of the court was a breadth of twenty cubits round about the temple on every side. ¹¹And the doors of the side chambers opened on the part of the platform that was left free, one door toward the north, and another door toward the south; and the breadth of the part that was left free was five cubits round about.
