Revelation 8:10-11 - The Third Trumpet

¹⁰ And the third angel sounded; and there fell from heaven a great star, burning like a lamp, and it fell on a third part of the rivers and on the fountains of waters. ¹¹ And the name of the star was called Bitterness. And a third part of the waters became bitter, and many men died by the waters, because they were bitter.
