Revelation 16:4-7

Etheridge(i) 4 And the third angel poured his vial upon the rivers, and upon the 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, and just; because thou hast judged these. 6 For the blood of saints and of prophets have they shed, and blood to them hast thou given to drink for they are worthy. 7 And I heard from the altar [voices] saying, Yes, Lord God Almighty! True and just is thy judgment.
