Revelation 16:5-7

Young's Literal Translation

⁵ and I heard the messenger of the waters, saying, `righteous, O Lord, art Thou, who art, and who wast, and who shalt be, because these things Thou didst judge,

⁶ because blood of saints and prophets they did pour out, and blood to them Thou didst give to drink, for they are worthy;'

⁷ and I heard another out of the altar, saying, `Yes, Lord God, the Almighty, true and righteous [are] Thy judgments.'
