Revelation 16:10

And the fourth angel poured out his vial upon the sun; and power was given unto him to scorch men with fire.

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.

And blasphemed the God of heaven because of their pains and their sores, and repented not of their deeds.

And the sixth angel poured out his vial upon the great river Euphrates; and the water thereof was dried up, that the way of the kings of the east might be prepared.
