Revelation 9:17-19

21st Century King James Version

¹⁷ And thus I saw the horses in the vision, and they that sat on them had breastplates of fire and of jacinth and brimstone; and the heads of the horses were as the heads of lions, and out of their mouths issued fire and smoke and brimstone.

¹⁸ By these three was a third part of men killed by the fire and by the smoke and by the brimstone, which issued out of their mouths.

¹⁹ For their power is in their mouth and in their tails; for their tails were like unto serpents and had heads, and with them they cause hurt.
