Revelation 16:12-14

The sixth Angel poured his bowl on the great Euphrates River: It dried up to nothing. The dry riverbed became a fine roadbed for the kings from the East. From the mouths of the Dragon, the Beast, and the False Prophet I saw three foul demons crawl out—they looked like frogs. These are demon spirits performing signs. They’re after the kings of the whole world to get them gathered for battle on the Great Day of God, the Sovereign-Strong.
