Revelation 16:11-13 Easy-to-Read Version (ERV)
11 They cursed the God of heaven because of their pain and the sores they had. But they refused to change their hearts and turn away from the evil things they did.
12 The sixth angel poured out his bowl on the great river Euphrates. The water in the river was dried up. This prepared the way for the rulers from the east to come. 13 Then I saw three evil spirits that looked like frogs. They came out of the mouth of the dragon, out of the mouth of the beast, and out of the mouth of the false prophet.
