Revelation 16:8-10

Amplified Bible, Classic Edition

⁸ Then the fourth [angel] emptied out his bowl upon the sun, and it was permitted to burn (scorch) humanity with [fierce, glowing] heat (fire).

⁹ People were severely burned (scorched) by the fiery heat, and they reviled and blasphemed the name of God, Who has control of these plagues, and they did not repent of their sins [felt no regret, contrition, and compunction for their waywardness, refusing to amend their ways] to give Him glory.

¹⁰ Then the fifth [angel] emptied his bowl on the throne of the beast, and his kingdom was [plunged] in darkness; and people gnawed their tongues for the torment [of their excruciating distress and severe pain]^(A)
