Revelation 16:12-16 - The Sixth Bowl
12 And the sixth angel poured out his cup on the great river Euphrates; and its water was dried up, that the way of the kings of the east might 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 that do signs, and they go forth to the kings of the whole world, to bring them together to the battle of that great day of God Almighty.
15 Behold, I come as a thief: blessed is he that watches, and keeps his garments, that he may not walk naked, and that men may not see his nakedness.
16 And they brought them together into a place that is called, in the Hebrew tongue, Armageddon.
