Revelation 16:12-21

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). Then the seventh angel poured out his bowl into the air, and a loud voice came out of the temple from the throne [of God], saying, “It is done. [It is all over, it is all accomplished, it has come.]” And there were flashes of lightning and loud rumblings and peals of thunder; and there was a massive earthquake—nothing like it has ever occurred since mankind originated on the earth, so severe and far-reaching was that earthquake. [Ex 19:16-18; Dan 12:1] The great city was split into three parts, and the cities of the nations fell. And God kept in mind Babylon the great, to give her the cup of the wine of His fierce and furious wrath. Then every island fled away, and no mountains could be found. And giant hailstones, as heavy as a talent, fell from the sky on the people; and people reviled and spoke abusively of God for the plague of the hail, because the plague was so very great. [Ex 9:22-25]
