Revelation 9:17-19

Douay-Rheims 1899 American Edition

¹⁷ 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.

¹⁸ 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.

¹⁹ 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.
