1 Kings 6:5-7

New International Version - UK

⁵ Against the walls of the main hall and inner sanctuary he built a structure around the building, in which there were side rooms. ⁶ The lowest floor was five cubits^[a] wide, the middle floor six cubits^[b] and the third floor seven.^[c] He made offset ledges around the outside of the temple so that nothing would be inserted into the temple walls.

⁷ In building the temple, only blocks dressed at the quarry were used, and no hammer, chisel or any other iron tool was heard at the temple site while it was being built.
