Revelation 16:4-7 - The Third Bowl
4 The third poured out his bowl upon the rivers and fountains of water, and they turned blood. 5 Then I heard the angel of the waters cry, "O holy One, who art and wast, just art thou in this thy sentence. 6 They poured out the blood of saints and prophets, and thou hast given them blood to drink! They deserve it!"
7 And I heard the altar cry, "Even so, Lord God almighty: true and just are thy sentences of doom."
