Revelation 9:18-20

Holman Christian Standard Bible

¹⁸ A third of the human race was killed by these three plagues—by the fire, the smoke, and the sulfur that came from their mouths. ¹⁹ For the power of the horses is in their mouths and in their tails, for their tails, which resemble snakes, have heads, and they inflict injury with them.

²⁰ The rest of the people, who were not killed by these plagues, did not repent of the works of their hands to stop worshiping demons^(A) and idols of gold, silver, bronze, stone, and wood, which are not able to see, hear, or walk.^(B)
