Revelation 16:4-7 - The Third Bowl
4 And the third poured out his phial on the rivers and fountains of waters, and they became blood. 5 And I heard the angel of the waters saying, Righteous art thou, who art, and who wast, the Gracious one, because thou hast judged thus. 6 For they have shed the blood of saints and prophets, and thou hast given them blood to drink. They are worthy.
7 And I heard another from the altar, saying, Yea, Lord God Almighty; true and righteous are thy judgments.
