1 Kings 6:5-8
6:5 He built an extension all around the walls of the temple’s main hall and holy place and constructed side rooms in it.
6:6 The bottom floor of the extension was seven and a half feet wide, the middle floor nine feet wide, and the third floor ten and a half feet wide. He made ledges on the temple’s outer walls so the beams would not have to be inserted into the walls.
6:7 As the temple was being built, only stones shaped at the quarry were used; the sound of hammers, pickaxes, or any other iron tool was not heard at the temple while it was being built.
6:8 The entrance to the bottom level of side rooms was on the south side of the temple; stairs went up to the middle floor and then on up to the third floor.
