Revelation 16:12-21 Revised Standard Version (RSV)
12 The sixth angel poured his bowl on the great river Euphra′tes, and its water was dried up, to prepare the way for the kings from the east. 13 And I saw, issuing from the mouth of the dragon and from the mouth of the beast and from the mouth of the false prophet, three foul spirits like frogs; 14 for they are demonic spirits, performing signs, who go abroad to the kings of the whole world, to assemble them for battle on the great day of God the Almighty. 15 (“Lo, I am coming like a thief! Blessed is he who is awake, keeping his garments that he may not go naked and be seen exposed!”) 16 And they assembled them at the place which is called in Hebrew Armaged′don.
17 The seventh angel poured his bowl into the air, and a loud voice came out of the temple, from the throne, saying, “It is done!” 18 And there were flashes of lightning, voices, peals of thunder, and a great earthquake such as had never been since men were on the earth, so great was that earthquake. 19 The great city was split into three parts, and the cities of the nations fell, and God remembered great Babylon, to make her drain the cup of the fury of his wrath. 20 And every island fled away, and no mountains were to be found; 21 and great hailstones, heavy as a hundredweight, dropped on men from heaven, till men cursed God for the plague of the hail, so fearful was that plague.
