1 Kings 6:6, 10

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.

He also built the stories against the whole house, each five cubits high; and they were fastened to the house with timbers of cedar.
