Revelation 8:11-12

11The star is named Wormwood; and a 1third of the waters became 2wormwood, and many people died from the waters because they were made bitter.

12The fourth angel sounded, and a 3third of the 4sun, a third of the 5moon, and a 6third of the 7stars were struck, so that a 8third of them would be darkened and the day would not shine for a 9third of it, and the night in the same way.
