Revelation 19:19

‘And I saw the beast, and the kings of the earth, and their armies, gathered together to make war against him that sat on the horse and against his army.'

There is no doubt about the aim of the forces of evil. Possibly in some way they still believe that they can prevent the coming of Christ and His final judgment. But probably it is just to indicate their defiance. There is no mention of an actual battle for their Enemy is irresistible. They are just floundering in their folly.

In Revelation 20:9 we are informed how these forces of evil warred against Him Who sat on the horse and against His army. They did it by attacking His people on earth. ‘They went up over the breadth of the earth, and surrounded the camp of the saints and the beloved city'. In other words they turned their vicious attentions on His people (Revelation 12:17). The camp of the saints has in mind God's people worldwide, depicted as though they were all together in one place. They are in tents because they are strangers and pilgrims on the earth. The beloved city (Psalms 78:68; Psalms 87:2) represents the true, believing Israel who are of course a part of the people of God (compare Revelation 11:1; Revelation 12:13; also Revelation 21:12).
