Sirach 21:19-21

New Revised Standard Version, Anglicised Catholic Edition

¹⁹ To a senseless person education is fetters on his feet,
    and like manacles on his right hand.
²⁰ A fool raises his voice when he laughs,
    but the wise^[a] smile quietly.
²¹ To the sensible person education is like a golden ornament,
    and like a bracelet on the right arm.
