Revelation 8:13 (KJV)

And the second angel sounded, and as it were a great mountain burning with fire was cast into the sea: and the third part of the sea became blood;

And the third part of the creatures which were in the sea, and had life, died; and the third part of the ships were destroyed.

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;

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.

And the fourth angel sounded, and the third part of the sun was smitten, and the third part of the moon, and the third part of the stars; so as the third part of them was darkened, and the day shone not for a third part of it, and the night likewise.
