Revelation 16:10-12 New International Reader's Version (NIRV)
10 The fifth angel poured out his bowl on the throne of the beast. The kingdom of the beast became very dark. People chewed on their tongues because they were suffering so much. 11 They spoke evil things against the God of heaven. They did this because of their pains and their sores. But they refused to turn away from the sins they had committed.
12 The sixth angel poured out his bowl on the great river Euphrates. Its water dried up to prepare the way for the kings from the East.
