Revelation 16:8-16

And the fourth poured out his bowl upon the sun; and it was given unto it to scorch men with fire. And men were scorched with great heat: and they blasphemed the name of God who hath the power over these plagues; and they repented not to give him glory. And the fifth poured out his bowl upon the throne of the beast; and his kingdom was darkened; and they gnawed their tongues for pain, and they blasphemed the God of heaven because of their pains and their sores; and they repented not of their works. And the sixth poured out his bowl upon the great river, the river Euphrates; and the water thereof was dried up, that the way might be made ready for the kings that come from the sunrising. 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, as it were frogs: for they are spirits of demons, working signs; which go forth unto the kings of the whole world, to gather them together unto the war of the great day of God, the Almighty. (Behold, I come as a thief. Blessed is he that watcheth, and keepeth his garments, lest he walk naked, and they see his shame.) And they gathered them together into the place which is called in Hebrew Har-Magedon.
