And the number of the army of horsemen was twenty thousand times ten thousand. And I heard the number of them. And thus I saw the horses in the vision: and they that sat on them, had breastplates of fire and of hyacinth and of brimstone, and the heads of the horses were as the heads of lions: and from their mouths proceeded fire, and smoke, and brimstone. And by these three plagues was slain the third part of men, by the fire and by the smoke and by the brimstone, which issued out of their mouths. For the power of the horses is in their mouths, and in their tails. For, their tails are like to serpents, and have heads: and with them they hurt.
