Revelation 16:10-12 Good News Translation (GNT)
10 Then the fifth angel poured out his bowl on the throne of the beast. Darkness fell over the beast's kingdom, and people bit their tongues because of their pain, 11 and they cursed the God of heaven for their pains and sores. But they did not turn from their evil ways.
12 Then the sixth angel poured out his bowl on the great Euphrates River. The river dried up, to provide a way for the kings who come from the east.
