Revelation 9:15-19

The Four Angels were untied and let loose, Four Angels all prepared for the exact year, month, day, and even hour when they were to kill a third of the human race. The number of the army of horsemen was twice ten thousand times ten thousand. I heard the count and saw both horses and riders in my vision: fiery breastplates on the riders, lion heads on the horses breathing out fire and smoke and brimstone. With these three weapons—fire and smoke and brimstone—they killed a third of the human race. The horses killed with their mouths and tails; their serpentlike tails also had heads that wreaked havoc.
