Revelation 16:8-11

ISV(i) 8 The fourth angel poured his bowl on the sun, which then was allowed to burn people with fire, 9 and they were burned by the fierce heat. They cursed the name of God, who has the authority over these plagues. They did not repent and give him glory.
10 The fifth angel poured his bowl on the throne of the beast. Its kingdom was plunged into darkness. People gnawed on their tongues in anguish 11 and cursed the God of heaven because of their pain-filled sores. But they did not repent of their behavior.
