Revelation 16:3-7

The second angel poured out his bowl into the sea, and it became blood like that of a dead man; and every living thing in the sea died.

Then the third angel poured out his bowl into the rivers and the springs of waters; and they became blood.

And I heard the angel of the waters saying, “Righteous are You, the One who is and who was, O Holy One, because You judged these things;

for they poured out the blood of saints and prophets, and You have given them blood to drink. They deserve it.”

And I heard the altar saying, “Yes, Lord God, the Almighty, true and righteous are Your judgments.”
