Sirach 22:9-11

New Revised Standard Version, Anglicised Catholic Edition

⁹ Whoever teaches a fool is like one who glues potsherds together,
    or who rouses a sleeper from deep slumber.
¹⁰ Whoever tells a story to a fool tells it to a drowsy man;
    and at the end he will say, ‘What is it?’
¹¹ Weep for the dead, for he has left the light behind;
    and weep for the fool, for he has left intelligence behind.
Weep less bitterly for the dead, for he is at rest;
    but the life of the fool is worse than death.
