10 And the third angel sounded, and there fell a great star from heaven burning as it were a lamp, and it fell upon the third part of the rivers and upon the fountains of waters. 11And 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.
