Revelation 16:8-11

Then the fourth angel poured out his bowl on the sun, causing it to scorch everyone with its fire. Everyone was burned by this blast of heat, and they cursed the name of God, who had control over all these plagues. They did not repent of their sins and turn to God and give him glory. Then the fifth angel poured out his bowl on the throne of the beast, and his kingdom was plunged into darkness. His subjects ground their teeth in anguish, and they cursed the God of heaven for their pains and sores. But they did not repent of their evil deeds and turn to God.
