1 Kings 6:6, 10

The nethermost story was five cubits broad, and the middle was six cubits broad, and the third was seven cubits broad; for on the outside he made offsets in the wall of the house round about, that the beams should not have hold in the walls of the house.

And he built the stories against all the house, each five cubits high: and they rested on the house with timber of cedar.
