Revelation 16:5-7

5And I heard the angel of the waters saying: “You are righteous, O Lord, The One who is and who was and who is to be, Because You have judged these things.

6For they have shed the blood of saints and prophets, And You have given them blood to drink. For it is their just due.”

7And I heard another from the altar saying, “Even so, Lord God Almighty, true and righteous are Your judgments.”
