Revelation 16:9-11

They were scorched by the fierce heat, and they cursed the name of God who had power over these plagues. They did not repent and give him glory. 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 anguish and cursed the God of heaven for their pain and sores. They did not repent of their deeds.
