Sirach 21:19-21

Common English Bible

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.
