Revelation 16:4-7

Amplified Bible

⁴ Then the third angel poured out his bowl into the rivers and the springs of water; and they turned into blood.^{(A) 5} And I heard the angel of the waters saying, “Righteous and just are You, Who are and Who were, O Holy One, because You judged these things; ⁶ for they have poured out the blood of the saints (God’s people) and the prophets, and You [in turn] have given them blood to drink. They deserve Your judgment.”^{(B) 7} And I heard [another from] the altar saying, “Yes, O Lord God, the Almighty [the Omnipotent, the Ruler of all], Your judgments are true and fair and righteous.”^(C)
