Revelation 16:12-21

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. And the seventh poured out his bowl upon the air; and there came forth a great voice out of the temple, from the throne, saying, It is done: and there were lightnings, and voices, and thunders; and there was a great earthquake, such as was not since there were men upon the earth, so great an earthquake, so mighty. And the great city was divided into three parts, and the cities of the nations fell: and Babylon the great was remembered in the sight of God, to give unto her the cup of the wine of the fierceness of his wrath. And every island fled away, and the mountains were not found. And great hail, every stone about the weight of a talent, cometh down out of heaven upon men: and men blasphemed God because of the plague of the hail; for the plague thereof is exceeding great.
