Revelation 16

13 An evil spirit that looked like a frog came out of the mouth of the dragon. One also came out of the mouth of the beast, and another out of the mouth of the false prophet. 14 These evil spirits had the power to work miracles. They went to every king on earth, to bring them together for a war against God All-Powerful. But that will be the day of God’s great victory.
