Revelation 16:3-6

Then the second angel poured out his bowl on the sea, and it became blood as of a dead man; and every living creature in the sea died. Then the third angel poured out his bowl on the rivers and springs of water, and they became blood. And I heard the angel of the waters saying: “You are righteous, O Lord, The One who is and who was and who is to be, Because You have judged these things. For they have shed the blood of saints and prophets, And You have given them blood to drink. For it is their just due.”
