King James Version
“And the third angel poured out his vial upon the rivers and fountains of waters; and they became blood.”
Context
1And I heard a great voice out of the temple saying to the seven angels, Go your ways, and pour out the vials of the wrath of God upon the earth.
2And the first went, and poured out his vial upon the earth; and there fell a noisome and grievous sore upon the men which had the mark of the beast, and them which worshipped his image.
3And the second angel poured out his vial upon the sea; and it became as the blood of a dead and every living soul died in the sea.
4And the third angel poured out his vial upon the rivers and fountains of waters; and they became blood.
5And I heard the angel of the waters say, Thou art righteous, O Lord, which art, and wast, and shalt be, because thou hast judged thus.
6For they have shed the blood of saints and prophets, and thou hast given them blood to drink; for they are worthy.
7And I heard another out of the altar say, Even so, Lord God Almighty, true and righteous thy judgments.
