Revelation 16:10-12

King James Version

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,

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

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.
