1. Whom he makes war against (v. 2): The indignation of the Lord is upon all nations; they are all in confederacy against God and religion, all in the interests of the devil, and therefore he is angry with them all, even with all the nations that forget him. He has long suffered all nations to walk in their own ways (Acts xiv. 16), but now he will no longer keep silence. As they have all had the benefit of his patience, so they must all expect now to feel his resentments. His fury is in a special manner upon all their armies, (1.) Because with them they have done mischief to the people of God; those are they that have made bloody work with them, and therefore they must be sure to have blood given them to drink. (2.) Because with them they hope to make their part good against the justice and power of God they trust to them as their defence, and therefore on them, in the first place, God's fury will come. Armies before God's fury are but as dry stubble before a consuming fire, though ever so numerous and courageous.
