Revelation 16:10-13

10The fifth poured out his bowl on the throne of the beast, and its kingdom was plunged into darkness. People gnawed their tongues because of their pain

11and blasphemed the God of heaven because of their pains and their sores, but they did not repent of their works.

12The sixth poured out his bowl on the great river Euphrates, and its water was dried up to prepare the way for the kings from the east.

13Then I saw three unclean spirits like frogs coming from the dragon’s mouth, from the beast’s mouth, and from the mouth of the false prophet.
