'Undisciplined' in the Bible

And we urge you, brothers and sisters, admonish the undisciplined, comfort the discouraged, help the weak, be patient toward all.

But we command you, brothers and sisters, in the name of our Lord Jesus Christ, to keep away from any brother who lives an undisciplined life and not according to the tradition they received from us.

For we hear that some among you are living an undisciplined life, not doing their own work but meddling in the work of others.
