Revelation 16:2-4

16:2 So the first angel went and poured out his bowl on the earth. Then ugly and painful sores appeared on the people who had the mark of the beast and who worshiped his image.

16:3 Next, the second angel poured out his bowl on the sea and it turned into blood, like that of a corpse, and every living creature that was in the sea died.

16:4 Then the third angel poured out his bowl on the rivers and the springs of water, and they turned into blood.
