Proverbs 29:15-17

Revised Standard Version

¹⁵ The rod and reproof give wisdom,
    but a child left to himself brings shame to his mother.
¹⁶ When the wicked are in authority, transgression increases;
    but the righteous will look upon their downfall.
¹⁷ Discipline your son, and he will give you rest;
    he will give delight to your heart.
