Revelation 16:9-11

9Thus people were scorched by the terrible heat, yet they blasphemed the name of God, who has ruling authority over these plagues, and they would not repent and give him glory.

10Then the fifth angel poured out his bowl on the throne of the beast so that darkness covered his kingdom, and people began to bite their tongues because of their pain.

11They blasphemed the God of heaven because of their sufferings and because of their sores, but nevertheless they still refused to repent of their deeds.
