Revelation 8:10-11 - The Third Trumpet

10 And the third angel sounded the trumpet, and a great star fell from heaven, burning as a lit torch, and it fell upon the third part of the rivers and upon the fountains of waters; 11 and the name of the star is called Wormwood; and the third part of the waters became wormwood; and many men died of the waters because they were made bitter.
