Revelation 16:11-15

and they blasphemed the God of heaven because of their pain 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. Har-Magedon (Armageddon)

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 entire 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 people will not see his shame.”)
