Thematic Bible: The army of horsemen

And the number of the armies of the horsemen was two myriads of myriads. And I heard their number. And so I saw the horses in the vision, and those sitting on them, having breastplates of fire, even dusky red and brimstone. And the heads of the horses were like the heads of lions. And out of their mouths issued fire and smoke and brimstone. By these three the third part of men was killed, by the fire, and by the smoke, and by the brimstone which issued out of their mouths. read more.
For their authority is in their mouth and in their tails. For their tails were like serpents with heads, and with them they do harm.
