Revelation 16:10-13

10The fifth angel poured his bowl on the throne of the beast. Its kingdom turned dark. People gnawed on their tongues in anguish

11and cursed the God of heaven for their pains and their sores. However, they would not stop what they were doing.

12The sixth angel poured his bowl on the great Euphrates River. The water in the river dried up to make a road for the kings from the east.

13Then I saw three evil spirits like frogs come out of the mouths of the serpent, the beast, and the false prophet.
