2 Peter 2:1-3

But there arose false prophets also among the people, as among you also there shall be false teachers, who shall privily bring in destructive heresies, denying even the Master that bought them, bringing upon themselves swift destruction. And many shall follow their lascivious doings; by reason of whom the way of the truth shall be evil spoken of. And in covetousness shall they with feigned words make merchandise of you: whose sentence now from of old lingereth not, and their destruction slumbereth not.
