Revelation 16:6

4And the third angel poured out his vial upon the rivers and fountains of waters; and they became blood.

5And I heard the angel of the waters say, Thou art righteous, O Lord, which art, and wast, and shalt be, because thou hast judged thus.

6For they have shed the blood of saints and prophets, and thou hast given them blood to drink; for they are worthy.

7And I heard another out of the altar say, Even so, Lord God Almighty, true and righteous are thy judgments.

8And the fourth angel poured out his vial upon the sun; and power was given unto him to scorch men with fire.
