TSK · Proverbs 19:18

The one who spares his rod hates his child, but the one who loves his child is diligent in disciplining him.

Do not withhold discipline from a child; even if you strike him with the rod, he will not die.

A rod and reproof impart wisdom, but a child who is unrestrained brings shame to his mother.

Endure your suffering as discipline; God is treating you as sons. For what son is there that a father does not discipline?
