Sirach 21:19

19 Doctrine unto fools is as fetters on the feet, and like manacles on the right hand.

Sirach 21:19 In-Context

17 They enquire at the mouth of the wise man in the congregation, and they shall ponder his words in their heart.

18 As is a house that is destroyed, so is wisdom to a fool: and the knowledge of the unwise is as talk without sense.

19 Doctrine unto fools is as fetters on the feet, and like manacles on the right hand.

20 A fool lifteth up his voice with laughter; but a wise man doth scarce smile a little.

21 Learning is unto a wise man as an ornament of gold, and like a bracelet upon his right arm.
