Revelation 16:4-7

21st Century King James Version

⁴ And the third angel poured out his vial upon the rivers and fountains of waters; and they became blood.

⁵ And I heard the angel of the waters say, “Thou art righteous, O Lord, who art, and wast, and shall be, because Thou hast judged thus;

⁶ for they have shed the blood of saints and prophets, and Thou hast given them blood to drink, for they are worthy.”

⁷ And I heard another out of the altar say, “Even so, Lord God Almighty; true and righteous are Thy judgments.”
