Revelation 16:8-16

Then the fourth angel poured out his bowl on the sun, and it was given power to scorch humanity with [raging] fire. People were [severely] burned by the great heat; and they reviled the name of God who has power over these plagues, but they did not repent [of their sin] and glorify Him. Then the fifth angel poured out his bowl on the throne of the beast, and his kingdom was plunged into darkness; and people gnawed their tongues because of the pain [of their excruciating anguish and severe torment], [Ex 10:21] and they blasphemed the God of heaven because of their anguish and their sores (abscesses, boils); and they did not repent of what they had done nor hate their wickedness. Then 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 coming of] the kings from the east. [Is 11:15, 16] And I saw three loathsome spirits like frogs, leaping from the mouth of the dragon (Satan) and from the mouth of the beast (Antichrist, dictator) and from the mouth of the false prophet; [Ex 8:3; 1 Kin 22:21-23] for they are [actually] the spirits of demons, performing [miraculous] signs. And they go out to the kings of the entire inhabited earth, to gather them together for the war of the great day of God, the Almighty. (“Behold, I am coming like a thief. Blessed is he who stays awake and who keeps his clothes [that is, stays spiritually ready for the Lord’s return], so that he will not be naked—spiritually unprepared—and men will not see his shame.”) [Matt 24:42-44; 1 Thess 5:2-4] And they (demons) gathered the kings and armies of the world together at the place which in Hebrew is called Har-Magedon (Armageddon).
