New American Standard Bible (©1995)
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.
