Revelation 16:3-6

The second angel poured out his bowl on the sea, and it became blood like that of a dead man, and every living thing in the sea died. The third angel poured out his bowl on the rivers and the springs of water, and they became blood. Then I heard the angel of the waters saying: “Holy One, you are the One who is and who was. You are right to decide to punish these evil people. They have poured out the blood of your holy people and your prophets. So now you have given them blood to drink as they deserve.”
