Revelation 16:10-13

10Then the fifth angel poured out his bowl on the throne of the wild animal. As a result, the whole kingdom that the wild animal ruled became dark. People were biting their tongues because of their great pain.

11They cursed the God of heaven because of their pain and because of the sores on their skin. But they did not stop doing bad things.

12Then the sixth angel poured out his bowl on the great Euphrates river. As a result, the river became dry. This prepared a way for kings from the east to march across it.

13Then I saw three bad spirits that looked like frogs. One bad spirit came out of the dragon's mouth. Another one came out of the first wild animal's mouth. The third one came out of the false prophet's mouth.
