Revelation 8:10-12

10The third angel sounded, and a great star 1fell from heaven, burning like a torch, and it fell on a 2third of the rivers and on the 3springs of waters. 11The star is named Wormwood; and a 4third of the waters became 5wormwood, and many people died from the waters because they were made bitter.

12The fourth angel sounded, and a 6third of the 7sun, a third of the 8moon, and a 9third of the 10stars were struck, so that a 11third of them would be darkened and the day would not shine for a 12third of it, and the night in the same way.
