Revelation 9:19-21 Revised Geneva Translation (RGT)
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.
20 And the remnant of man who were not killed by these plagues did not repent of the works of their hands (so that they would not worship devils, and idols of gold and of silver and of brass and of stone and of wood, which neither can see, nor hear, nor go).
21 Also they did not repent of their murder, and of their sorcery, nor of their fornication, nor of their theft.
Revelation 9:19-21 New International Version (NIV)
19 The power of the horses was in their mouths and in their tails; for their tails were like snakes, having heads with which they inflict injury.
20 The rest of mankind who were not killed by these plagues still did not repent of the work of their hands; they did not stop worshiping demons, and idols of gold, silver, bronze, stone and wood—idols that cannot see or hear or walk. 21 Nor did they repent of their murders, their magic arts, their sexual immorality or their thefts.
