Revelation 8.8
From Landmark
8 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;
9 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.
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;
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.
