Revelation 16:9-12

16:9  And men were scorched with great heat, and blasphemed the name of God, which hath power over these plagues: and they repented not to give him glory.

16:10  And the fifth angel poured out his vial upon the seat of the beast; and his kingdom was full of darkness; and they gnawed their tongues for pain,

16:11  And blasphemed the God of heaven because of their pains and their sores, and repented not of their deeds.

16:12  And the sixth angel poured out his vial upon the great river Euphrates; and the water thereof was dried up, that the way of the kings of the east might be prepared.
