1 Kings 6:5-8

5Against the wall of the House he built a side-structure surrounding both the Temple and the inner Sanctuary; thus he made side-chambers all around.

6The lowest story was five cubits wide, the middle was six cubits wide, and the third was seven cubits wide. All around on the outside he provided offset ledges in the wall of the House, so that the beams would not be inserted into the walls of the House.

7For the House, while being constructed, was built of stone finished at the quarry; with neither hammer, axe nor any iron tool heard in the House during its construction.

8The doorway to the lowest story of the side chambers was on the right side of the House. They went up by winding stairs to the middle story, and from the middle to the third.
