Isaiah 33:3,4

At the noise of the tumult Which shall be made upon the angel's destroying the army; the people fled Namely, those of the army who escaped that stroke. At the lifting up of thyself To execute judgment; the nations were scattered The people of divers nations which made up Sennacherib's army. And your spoil That treasure which you have raked together by spoiling divers people; shall be gathered By the Jews at Jerusalem, when you shall be forced to flee away with all possible speed, leaving your spoils behind you; like the gathering of the caterpillar As caterpillars gather and devour all the fruits of the earth, which was a common plague in those countries; as the running to and fro of locusts, &c. As locusts, especially when they are armed by commission from God, come with great force, and run hither and thither devouring every thing before them; shall he run upon them Namely, Hezekiah, with his people, shall thus eagerly run to the spoil of the Assyrian camp, and shall take it.
