Thematic Bible: The army of horsemen

And the number of the armies of the horsemen was two hundred thousand thousand; I heard the number of them. And thus I saw the horses in the vision, and those who sat on them, having breastplates of a fiery, and a dark blue, and a brimstone color; and the heads of the horses were as the heads of lions, and out of their mouths issued fire, and smoke, and brimstone. By these three plagues was the third part of men killed, by the fire, and the smoke, and the brimstone, which issued out of their mouths. read more.
For the power of the horses is in their mouth, and in their tails; for their tails are like to serpents, having heads; and with them they do hurt.
