2 Peter 2:18-20

2:18 For by speaking high-sounding but empty words they are able to entice, with fleshly desires and with debauchery, people who have just escaped from those who reside in error. 2:19 Although these false teachers promise such people freedom, they themselves are enslaved to immorality. For whatever a person succumbs to, to that he is enslaved. 2:20 For if after they have escaped the filthy things of the world through the rich knowledge of our Lord and Savior Jesus Christ, they again get entangled in them and succumb to them, their last state has become worse for them than their first.
