Revelation 16:12-16

The sixth angel poured out his bowl on the great river Euphrates. The water in the river was dried up. This prepared the way for the rulers from the east to come. Then I saw three evil spirits that looked like frogs. They came out of the mouth of the dragon, out of the mouth of the beast, and out of the mouth of the false prophet. These evil spirits are the spirits of demons. They have power to do miracles. They go out to the rulers of the whole world to gather them for battle on the great day of God All-Powerful. “Listen! I will come at a time you don’t expect, like a thief. Great blessings belong to those who stay awake and keep their clothes with them. They will not have to go without clothes and be ashamed for people to see them.” Then the evil spirits gathered the rulers together to the place that in Hebrew is called Armageddon.
