The Building of the Temple
5Against the wall of the house he built stories encompassing the walls of the house around both the main room and the inner sanctuary; so 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; for on the outside he made offsets in the wall of the house all around so that the beams would not be inserted into the walls of the house.
