Revelation 16:9-11

9and people were scorched by the intense heat. So they blasphemed the name of God, who has the power over these plagues, and they did not repent and give him glory.

10The fifth poured out his bowl on the throne of the beast, and its kingdom was plunged into darkness. People gnawed their tongues because of their pain

11and blasphemed the God of heaven because of their pains and their sores, but they did not repent of their works.
