Revelation 16:2-4

Living Bible

² So the first angel left the temple and poured out his flask over the earth, and horrible, malignant sores broke out on everyone who had the mark of the Creature and was worshiping his statue.

³ The second angel poured out his flask upon the oceans, and they became like the watery blood of a dead man; and everything in all the oceans died.

⁴ The third angel poured out his flask upon the rivers and springs and they became blood.
