Revelation 9:19-21 Living Bible (TLB)
19 Their power of death was not only in their mouths, but in their tails as well, for their tails were similar to serpents’ heads that struck and bit with fatal wounds.
20 But the men left alive after these plagues still refused to worship God! They would not renounce their demon-worship, nor their idols made of gold and silver, brass, stone, and wood—which neither see nor hear nor walk! 21 Neither did they change their mind and attitude about all their murders and witchcraft, their immorality and 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.
