Revelation 16:9-11

They were seared by the intense heat and they cursed the name of God, who had control over these plagues, but they refused to repent and glorify him. The fifth angel poured out his bowl on the throne of the beast, and its kingdom was plunged into darkness. People gnawed their tongues in agony and cursed the God of heaven because of their pains and their sores, but they refused to repent of what they had done.
