'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.
The side chambers were in three stories, one above another, and thirty in each story; and the side chambers extended to the wall which stood on their inward side all around, that they might be fastened, and not be fastened into the wall of the temple itself.
The side chambers surrounding the temple were wider at each successive story. Because the structure surrounding the temple went upward by stages on all sides of the temple, therefore the width of the temple increased as it went higher; and thus one went up from the lowest story to the highest by way of the second story.
