The wind goeth toward the south, and turneth about unto the north; it whirleth about continually, and the wind returneth again according to his circuits.
According to (Hebrew, upon) his circuits - i:e., it returns afresh to its former circuits, however many be its previous veerings about. The north and south winds are the two prevailing winds in Palestine and Egypt. The circuits of the winds are here made the symbol of man's existence ever revolving in the circle of vanity, and unable to move forward beyond it. As cast and west are noticed us to the sun (Ecclesiastes 1:5), so north and south as to the wind.
