IV. Here is the terrible execution done by this formidable army, 1. In the country, v. 3. View the army in the front, and you will see a fire devouring before them; they consume all as if they breathed fire. View it in the rear, and you will see those that come behind as furious as the foremost: Behind them a flame burns. When they are gone, then it will appear what destruction they have made. Look upon the fields that they have not yet invaded, and they are as the garden of Eden, pleasant to the eye, and full of good fruits; they are the pride and glory of the country. But look upon the fields that they have eaten up and they are as a desolate wilderness; one would not think that these had ever been like the former, and yet so they were perhaps but the day before, or that those should ever be made like these, and yet so they shall be perhaps by to-morrow night; yea, and nothing shall escape them than can possibly be made food for them. Let none be proud of the beauty of their grounds any more than of their bodies, for God can soon change the face of both. 2. In the city. They shall climb the wall (v. 7), they shall run upon the houses, and enter in at the windows like a thief (v. 9); when Egypt was plagued with locusts, they filled Pharaoh's houses and the houses of his servants, Exod. x. 5, 6. The locusts out of the bottomless pit, Satan's emissaries, and missionaries of the man of sin, do as these locusts. God's judgments too, when they come with commission, cannot be kept out with bars and bolts; they will find or force their way.
