Rivers and springs become blood; angel of waters declares God's righteousness.
דָּם (dam, H1818); מַיִם (mayim, H4325)
ποταμός (potamos, G4215); ἄγγελος (angelos, G32); δικαιοσύνη (dikaiosyne, G1343)
And the third angel poured out his vial upon the rivers and fountains of waters; and they became blood.
And 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.
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 out of the altar say, Even so, Lord God Almighty, true and righteous are thy judgments.
