Har-Magedon (Armageddon)

13 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; 14 for they are spirits of demons, performing signs, which go out to the kings of the entire world, to gather them together for the war of the great day of God, the Almighty. 15 (“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 people will not see his shame.”) 16 And they gathered them together to the place which in Hebrew is called Har-Magedon.

The Seventh Bowl of Wrath

17 Then the seventh angel poured out his bowl upon 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 and sounds and peals of thunder; and there was a great earthquake, such as there had not been since mankind came to be upon the earth, so great an earthquake was it, and so mighty. 19 The great city was split into three parts, and the cities of the nations fell. Babylon the great was remembered in the sight of God, to give her the cup of the wine of His fierce wrath. 20 And every island fled, and no mountains were found. 21 And huge hailstones, weighing about a talent each, came down from heaven upon people; and people blasphemed God because of the plague of the hail, because the hailstone plague was extremely severe.
