Revelation 16:17

13I 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, something like frogs;

14for they are spirits of demons, performing signs, which go out to the kings of the whole inhabited earth, to gather them together for the war of that great day of God the Almighty.

15“Behold, I come like a thief. Blessed is he who watches, and keeps his clothes, so that he doesn’t walk naked, and they see his shame.”

16He gathered them together into the place which is called in Hebrew, “Harmagedon”.

17The seventh poured out his bowl into the air. A loud voice came out of the temple of heaven, from the throne, saying, “It is done!”

18There were lightnings, sounds, and thunders; and there was a great earthquake such as has not happened since there were men on the earth—so great an earthquake and so mighty.

19The great city was divided into three parts, and the cities of the nations fell. Babylon the great was remembered in the sight of God, to give to her the cup of the wine of the fierceness of his wrath.

20Every island fled away, and the mountains were not found.

21Great hailstones, about the weight of a talent, came down out of the sky on people. People blasphemed God because of the plague of the hail, for this plague was exceedingly severe.
