Revelation 16:4-9

4Then the third angel poured out his bowl on the rivers and springs, and they became blood.

5And I heard the angel who had authority over all water saying, “You are just, O Holy One, who is and who always was, because you have sent these judgments.

6Since they shed the blood of your holy people and your prophets, you have given them blood to drink. It is their just reward.”

7And I heard a voice from the altar, saying, “Yes, O Lord God, the Almighty, your judgments are true and just.”

8Then the fourth angel poured out his bowl on the sun, causing it to scorch everyone with its fire.

9Everyone was burned by this blast of heat, and they cursed the name of God, who had control over all these plagues. They did not repent of their sins and turn to God and give him glory.
