1Now there were also false prophets among the people, just as there will be false teachers among you. They will secretly introduce destructive heresies, even denying the Master who bought them — bringing swift destruction on themselves.
2Many will follow in their depravity, and because of them the way of truth will be defamed.
3In their greed, these false teachers will exploit you with deceptive words. The longstanding verdict against them remains in force, and their destruction does not sleep.
— 2 Peter 2:1-3
