5 Bible Verses about Children, Disciplining

He who keeps back his rod is unkind to his son: the loving father gives punishment with care.

It is for your training that you undergo these things; God is acting to you as a father does to his sons; for what son does not have punishment from his father? But if you have not that punishment of which we all have our part, then you are not true sons, but children of shame. And again, if the fathers of our flesh gave us punishment and had our respect, how much more will we be under the authority of the Father of spirits, and have life?read more.
For they truly gave us punishment for a short time, as it seemed good to them; but he does it for our profit, so that we may become holy as he is. At the time all punishment seems to be pain and not joy: but after, those who have been trained by it get from it the peace-giving fruit of righteousness.

Give your son training while there is hope; let not your heart be purposing his death.

Foolish ways are deep-seated in the heart of a child, but the rod of punishment will send them far from him.

Do not keep back training from the child: for even if you give him blows with the rod, it will not be death to him.
