12 And the sixth angel poured out his bowl upon the great river, the Euphrates; and its water was dried up, that the way might be prepared for the kings from the east.
13 And I saw coming out of the mouth of the dragon and out of the mouth of the beast and out of the mouth of the false prophet, three unclean spirits like frogs; 14 for they are spirits of demons, performing signs, which go out to the kings of the whole world, to gather them together for the war of the great day of God, the Almighty. 15 (“Behold, I am coming like a thief. Blessed is the one who stays awake and keeps his garments, lest he walk about naked and men see his shame.”) 16 And they gathered them together to the place which in Hebrew is called HarMagedon.
