The rod and reproof give wisdom, but a boy left to himself shames his mother.
In context
13The poor man and the man of extortion meet together; Yahweh gives light to the eyes of both. 14A king who judges the poor with truth—his throne will stand forever. 15The rod and reproof give wisdom, but a boy left to himself shames his mother. 16When the wicked grow many, offenses grow many, but the righteous will see their downfall. 17Discipline your son and he will give you rest; he will bring delights to your soul.
