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

       The power of these horses is in their mouths and their tails. (Their tails have heads like snakes which they use to hurt people.)
