The Second Trumpet

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 (Rev. 8:8, 9).
In the first trumpet, we see hail, fire, and blood, cast upon the earth, and some trees and all green grass burnt up. In the second trumpet, a great mountain, as it were (that is, something similar to a great burning mountain), is cast into the sea, when the third part of the sea becomes blood, a third of the living creatures in the sea die, and a third of the ships are destroyed. In the first trumpet, the earth, trees, grass are affected; and in the second, the sea, its creatures, and its ships: both are fiery, burning judgments.
The great burning mountain may be a symbol of power removed from its accustomed place, and thrown into that which brings terrible judgment upon the people.
