RKJNT(i)
4 And the third angel poured out his bowl upon the rivers and springs of water; and they became blood.
5 And I heard the angel of the waters say, You are righteous, you who are, and were, O Holy One, because you have judged thus.
6 For they have shed the blood of saints and prophets, and you have given them blood to drink; for such is their due.
