'Story' in the Bible

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.

The door for the middle side-chambers was in the right side of the house: and they went up by winding stairs into the middle'story , and out of the middle into the third.
