Revelation 16:4-7 - The Third Bowl
4 The third emptied his bowl upon the rivers and the springs of water, and they turned into blood. 5 Then I heard the angel of the waters say, "You are just in pronouncing this sentence, you who are and were, the Holy One; 6 for they shed the blood of your people and prophets, and you have given them blood to drink, as they deserve."
7 And I heard the altar answer, "Yes, Lord God Almighty! Your sentences are true and just."
