Then the angel of the LORD went forth, and smote in the camp of the Assyrians a hundred and fourscore and five thousand: and when they arose early in the morning, behold, they were all dead corpses. Isaiah 37:36
What happened when the first trumpet blew (Rev 8)?
Hail, fire, and blood burn all grass and 1/3 of trees
The first angel sounded, and there followed hail and fire mingled with blood, and they were cast upon the earth:
and the third part of trees was burnt up, and all green grass was burnt up. Revelation 8:7
