{21:22} Doctrine to the senseless is like fetters on the feet, and like chains on the right hand.
{21:23} A foolish man lifts up his voice in laughter. But a wise man will not even laugh quietly to himself.
{21:24} Doctrine is to the prudent like a gold ornament, and like an armband on the right arm.
{21:25} The feet of the foolish step easily into his neighbor’s house. But an experienced man will be apprehensive in the presence of the powerful.
{21:26} A senseless man will gaze through a window into the house. But a man who has been well-taught will stand outside.
{21:27} It is foolish for a man to listen through the door. And a prudent man will be grieved at this disgrace.
