Revelation 9:16-18

16The soldiers on horses numbered 20,000 times 10,000. I heard how many there were.

17In the vision that I had, the horses and their riders looked like this: The riders had breastplates that were fiery red, pale blue, and yellow. The horses had heads like lions. Fire, smoke, and sulfur came out of their mouths.

18These three plagues—the fire, smoke, and sulfur which came out of their mouths—killed one-third of humanity.
