Sirach 21:20

20 Fools raise their voice in laughter, but clever people will smile subtly in silence.

Sirach 21:20 In-Context

18 Like a house in disrepair, so is wisdom to the foolish, and the knowledge of ignorant people will not stand up to examination.

19 Education is shackles on the feet of the ignorant, like manacles on their hand.

20 Fools raise their voice in laughter, but clever people will smile subtly in silence.

21 To the prudent, education is like a gold ornament, like a bracelet on the arm.

22 The foolish enter quickly into a house, but experienced people will be ashamed to do so.
