Revelation 16:2-3, 5-7

So 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. [Ex 9:10, 11; Deut 28:35] The 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.

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; 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.” [Ps 79:3] 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.” [Ps 119:137]
