Revelation 16:2-6

2So the first angel went and poured out his bowl on the earth; and loathsome and malignant sores came on the people who had the mark of the beast and who worshiped his image.

3The second angel poured out his bowl into the sea, and it turned into blood like that of a corpse [foul and disgusting]; and every living thing in the sea died.

4Then the third angel poured out his bowl into the rivers and the springs of water; and they turned into blood.

5And 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;

6for 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.”
