300 Foxes and a Donkey's Jawbone
It's interesting to wonder what would cause all of the kings of the earth to rise up in battle against the King of Kings and Lord of Lords, when he returns to the earth, as has been prophesied and taught around the world for over 2,000 years.
The first five trumpets and vials are all part of the first of three woes. Blowing the sixth trumpet and pouring out the sixth vial of wrath is described as the second woe. The seventh trumpet/vial is the third woe.
The fifth trumpet/vial involves an army of horse-sized armor-plated locusts which are probably at least as terrifying as the Xenomorphs in the Alien franchise.
