Revelation 9:17-19

Revised Geneva Translation

¹⁷ And thus I saw the horses in a vision - and those who sat on them - having fiery breastplates of hyacinth and of brimstone. And the heads of the horses were as the heads of lions. And out of their mouths went forth fire and smoke and brimstone.

¹⁸ By these three was a third of mankind killed; that is, of the fire and of the smoke and of the brimstone which came out of their mouths.

¹⁹ For their power is in their mouths, and in their tails. For their tails were like serpents; and had heads with which they do harm.
