Sirach 21:18

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.

Sirach 21:18 In-Context

16 The talking of a fool is like a burden in the way: but grace shall be found in the lips of the wise.

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.
