Revelation 8:7-11

The first sounded, and there was hail and fire mixed with blood, and it was hurled to the earth; and a third of the earth was burned up, and a third of the trees were burned up, and all the green grass was burned up.

The second angel sounded, and something like a great mountain burning with fire was hurled into the sea; and a third of the sea became blood,

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

The third angel sounded, and a great star fell from heaven, burning like a torch, and it fell on a third of the rivers and on the springs of waters.

The star is named Wormwood; and a third of the waters became wormwood, and many people died from the waters because they were made bitter.
