'Teachers' in the Bible

But false prophets arose among the people, just as there will be false teachers among you. These false teachers will infiltrate your midst with destructive heresies, even to the point of denying the Master who bought them. As a result, they will bring swift destruction on themselves.

And many will follow their debauched lifestyles. Because of these false teachers, the way of truth will be slandered.

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.
