And the third poured out his vial upon the rivers and the fountains of waters; and there was made blood. And I heard the angel of the waters saying: Thou art just, O Lord, who art, and who wast, the Holy One, because thou hast judged these things: For they have shed the blood of saints and prophets, and thou hast given them blood to drink; for they are worthy. And I heard another, from the altar, saying: Yea, O Lord God Almighty, true and just are thy judgments.
Revelation 16:4-7
