Revelation 16:10-11

10Then the fifth angel poured out his bowl on the throne of the beast, and his kingdom was plunged into darkness; and people gnawed their tongues because of the pain [of their excruciating anguish and severe torment],

11and they blasphemed the God of heaven because of their anguish and their sores (abscesses, boils); and they did not repent of what they had done nor hate their wickedness.
