'Story' in the Bible

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.

The doorway for the lowest side chamber was on the right side of the house; and they would go up by winding stairs to the middle story, and from the middle to the third.
