And the sixth angel poured out his vial upon that great river Euphrates; and dried up the water thereof, that a way might be prepared for the kings from the rising of the sun. And I saw from the mouth of the dragon, and from the mouth of the beast, and from the mouth of the false prophet, three unclean spirits like frogs. For they are the spirits of devils working signs, and they go forth unto the kings of the whole earth, to gather them to battle against the great day of the Almighty God.
Revelation 16:12-14
