Revelation 9:19-21 For their authority is in their mouth and in their tails. For their tails were like serpents with heads, and with them they do harm.

MKJV⁽ⁱ⁾ ¹⁹ For their authority is in their mouth and in their tails. For their tails were like serpents with heads, and with them they do harm. ²⁰ And the rest of the men who were not killed by these plagues still did not repent of the works of their hands, that they should not worship demons, and golden, and silver, and bronze, and stone, and wooden idols (which neither can see, nor hear, nor walk). ²¹ And they did not repent of their murders, nor of their sorceries, nor of their fornication, nor of their thefts.
