And I heard a great voice out of the temple saying to the seven angels, Go your ways, and pour out the bowls of the wrath of God upon the earth. And the first went, and poured out his bowl upon the earth; and there fell foul and evil sores upon the men who had the mark of the beast, and upon them who worshiped his image.

And the second angel poured out his bowl upon the sea; and it became as the blood of a dead man; and every living thing died in the sea.

And the third angel poured out his bowl upon the rivers and fountains of waters; and they became blood.

And I heard the angel of the waters say, You are righteous, O Lord, who is, and was, and shall be, because you have judged thus. For they have shed the blood of saints and prophets, and you have given them blood to drink; for they are deserving of it. And I heard another out of the altar say, Even so, Lord God Almighty, true and righteous are your judgments.
(Revelation 16:1-7)
