Revelation 16:12-14 Revised Geneva Translation (RGT)
12 And the sixth angel poured out his vial upon the great river Euphrates. And the water thereof dried up, so the way of the Kings of the East would be prepared.
13 And I saw three unclean spirits, like frogs, come out of the mouth of the dragon, and out of the mouth of the beast, and out of the mouth of the false prophet.
14 For they are the spirits of demons, working miracles to go to the kings of the earth; and of the whole world, to gather them to the battle on that great Day of God Almighty.
