They were seared by the intense heat and they cursed the name of God, who had control over these plagues, but they refused to repent and glorify him.
NIV
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.
AMP
And men were scorched with great heat, and blasphemed the name of God, which hath power over these plagues: and they repented not to give him glory.
KJV
