Revelation 16:4-9

4And the third poured out his bowl into the rivers and the fountains of the waters; and it became blood. 5And I heard the angel of the waters saying, Righteous art thou, who art and who wast, thou Holy One, because thou didst thus judge: 6for they poured out the blood of saints and prophets, and blood hast thou given them to drink: they are worthy. 7And I heard the altar saying, Yea, O Lord God, the Almighty, true and righteous are thy judgments.

8And the fourth poured out his bowl upon the sun; and it was given unto it to scorch men with fire. 9And men were scorched with great heat: and they blasphemed the name of God who hath the power over these plagues; and they repented not to give him glory.
