Revelation 16:4-16

Then the third angel poured out his bowl into the rivers and the springs of waters; and they became blood. And I heard the angel of the waters saying, “Righteous are You, who are and who were, O Holy One, because You judged these things; for they poured out the blood of saints and prophets, and You have given them blood to drink. They deserve it.” And I heard the altar saying, “Yes, O Lord God, the Almighty, true and righteous are Your judgments.” The fourth angel poured out his bowl upon the sun, and it was given to it to scorch men with fire. Men were scorched with fierce heat; and they blasphemed the name of God who has the power over these plagues, and they did not repent so as to give Him glory. Then the fifth angel poured out his bowl on the throne of the beast, and his kingdom became darkened; and they gnawed their tongues because of pain, and they blasphemed the God of heaven because of their pains and their sores; and they did not repent of their deeds. The sixth angel poured out his bowl on the great river, the Euphrates; and its water was dried up, so that the way would be prepared for the kings from the east. 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 like frogs; for they are spirits of demons, performing signs, which go out to the kings of the whole world, to gather them together for the war of the great day of God, the Almighty. (“Behold, I am coming like a thief. Blessed is the one who stays awake and keeps his clothes, so that he will not walk about naked and men will not see his shame.”) And they gathered them together to the place which in Hebrew is called Har-Magedon.
