Revelation 16:4-7 - The Third Bowl
4 And the third poured out his bowl upon the rivers and fountains of the waters; and they became blood. 5 And I heard the angel of the waters saying, Thou art worthy, who is, and who was, the Holy One, because thou hast judged these things; 6 because they shed the blood of saints and of prophets, and thou hast given them blood to drink; they are worthy.
7 And I heard one speaking from the altar, Yes, Lord God Almighty, true and righteous are thy judgments.
