'Discipline' in the Bible

But I discipline my body and subjugate [it], lest somehow [after] preaching to others, myself should become disqualified.

And fathers, do not make your children angry, but bring them up in the discipline and instruction of the Lord.

And have you completely forgotten the exhortation which instructs you as sons? "My son, do not make light of the Lord's discipline, or give up [when you] are corrected by him.

Endure [it] for discipline. God is dealing with you as sons. For what son [is there] whom a father does not discipline?

But if you are without discipline, in which all [legitimate sons] have become participants, then you are illegitimate and not sons.

Now all discipline seems for the moment not to be joyful but painful, but later it yields the peaceful fruit of righteousness for those who are trained by it.

As many as I love, I reprove and discipline. Be zealous, therefore, and repent!
