Revelation 8:10-12

10Then the third angel blew his trumpet, and a huge star burning like a torch fell from the sky; it landed on a third of the rivers and on the springs of water.

11(Now the name of the star is Wormwood.) So a third of the waters became wormwood, and many people died from these waters because they were poisoned.

12Then the fourth angel blew his trumpet, and a third of the sun was struck, and a third of the moon, and a third of the stars, so that a third of them were darkened. And there was no light for a third of the day and for a third of the night likewise.
