Revelation 8:9-11

Revised Standard Version Catholic Edition

⁹ and a third of the sea became blood, a third of the living creatures in the sea died, and a third of the ships were destroyed.

¹⁰ The third angel blew his trumpet, and a great star fell from heaven, blazing like a torch, and it fell on a third of the rivers and on the fountains of water. ¹¹ The name of the star is Wormwood. A third of the waters became wormwood, and many men died of the water, because it was made bitter.
