Charles H. Spurgeon on Psalms 109:23

I am tossed up and down as the locust. Although the locusts have sufficient strength of flight to remain on the wing for a considerable period, and to pass over great distances, they have little or no command over the direction of their flight, always travel with the wind, in the same way as the quail. So entirely are they at the mercy of the wind, that if a sudden gust arises the locusts are tossed about in the most helpless manner; and if they should happen to come across one of the circular air currents that are so frequently found in the countries which they inhabit, they are whirled round and round without the least power of extricating themselves. —J.G. Wood.
