Revelation 16:3-6

3The second angel poured out his bowl on the sea, and it turned into blood like that of a dead person, and every living thing in the sea died. 4The third angel poured out his bowl on the rivers and springs of water, and they became blood. 5Then I heard the angel in charge of the waters say: “You are just in these judgments, O Holy One, you who are and who were; 6for they have shed the blood of your holy people and your prophets, and you have given them blood to drink as they deserve.”
