'Winding' in the Bible

The entrance to the lowest side chamber was on the right [or south] side of the house; and they would go up winding stairs to the middle [level], and from the middle to the third.

In that day the Lord will punish Leviathan the fleeing serpentWith His fierce and great and mighty sword [rescuing Israel from her enemy],Even Leviathan the twisted serpent;And He will kill the dragon who lives in the sea.

The side chambers became wider at each successive level as they encompassed the temple. Because the structure surrounding the temple went higher by stages on all sides of the temple, for that reason the width of the temple increased as it went higher; and thus one went up from the lowest story to the highest one by way of the second story.
