Revelation 16:12-16

¶ And the sixth angel poured out his vial into the great river Euphrates; and its water was dried up, that the way of the kings from the rising of the sun might be prepared. 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. For they are spirits of demons, working miracles, which go forth unto the kings of the earth and of the whole world to gather them to the battle of that great day of God Almighty. Behold, I come as a thief. Blessed is he that watches and keeps his garments lest he walk naked, and they see his shame. And he gathered them together into the place which in Hebrew is called, Armageddon.
