Revelation 16:5-7

American Standard Version

⁵ And I heard the angel of the waters saying, Righteous art thou, who art and who wast, thou Holy One, because thou didst thus ^[a]judge: ⁶ for they poured out the blood of saints and prophets, and blood hast thou given them to drink: they are worthy. ⁷ And I heard the altar saying, Yea, O Lord God, the Almighty, true and righteous are thy judgments.
