Revelation 9:18-20

Darby Translation

¹⁸ By these three plagues were the third part of men killed, by the fire and the smoke and the brimstone which goes out of their mouths.

¹⁹ For the power of the horses is in their mouth and in their tails: for their tails [are] like serpents, having heads, and with them they injure.

²⁰ And the rest of men who were not killed with these plagues repented not of the works of their hands, that they should not worship demons, and the golden and silver and brazen and stone and wooden idols, which can neither see nor hear nor walk.
