Proverbs 17:25-28

A foolish son is a grief to his father, And bitterness to her that bare him. Also to punish the righteous is not good, Nor to smite the noble for their uprightness. He that spareth his words hath knowledge; And he that is of a cool spirit is a man of understanding. Even a fool, when he holdeth his peace, is counted wise; When he shutteth his lips, he is esteemed as prudent.
