1 Kings 6:5-6

Against the wall of the house he built stories encompassing the walls of the house around both the nave and the inner sanctuary; thus he made side chambers all around. The lowest story was five cubits wide, and 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 in order that the beams would not be inserted in the walls of the house.
