'Riders' in the Bible

This was how I saw the horses in my vision: The riders wore breastplates that had the color of fire, sapphire, and sulfur. The heads of the horses were like lions' heads, and fire, smoke, and sulfur came out of their mouths.

so that you may eat the flesh of kings, the flesh of commanders, the flesh of mighty men, the flesh of horses and of their riders, and the flesh of everyone, both free and slave, small and great.”
