MLV(i)
4 And the third messenger poured out his bowl into the rivers and the springs of the waters, and it became blood.
5 And I heard the messenger of the waters saying, You are righteous, who is and who was, the Holy One, because you judged these things;
6 because they poured out the blood of holy-ones and prophets and you gave blood to them to drink because they are worthy.
7 And I heard from the altar saying, Yes, O Lord God, the Almighty, your judgments are true and righteous.
