Revelation 9:18-20

New Revised Standard Version, Anglicised Catholic Edition

¹⁸ By these three plagues a third of humankind was killed, by the fire and smoke and sulphur coming out of their mouths. ¹⁹ For the power of the horses is in their mouths and in their tails; their tails are like serpents, having heads; and with them they inflict harm.

²⁰ The rest of humankind, who were not killed by these plagues, did not repent of the works of their hands or give up worshipping demons and idols of gold and silver and bronze and stone and wood, which cannot see or hear or walk.
