Revelation 16:12-14

12Then the sixth angel poured out his bowl on the great river, the Euphrates; and its water was dried up, so that the way would be prepared for [the coming of] the kings from the east.

13And I saw three loathsome spirits like frogs, leaping from the mouth of the dragon (Satan) and from the mouth of the beast (Antichrist, dictator) and from the mouth of the false prophet;

14for they are [actually] the spirits of demons, performing [miraculous] signs. And they go out to the kings of the entire inhabited earth, to gather them together for the war of the great day of God, the Almighty.
