Revelation 8:10-11 - The Third Trumpet
10 And, the third messenger, sounded; and there fell, out of heaven, a great star, burning as a torch, and it fell upon the third of the rivers, and upon the fountains of waters. 11 And, the name of the star, is called Wormwood; and the third of the waters became wormwood, and many of the men died of the waters, because they were made bitter.
