Sirach 22:13-15

Revised Standard Version Catholic Edition

¹³ Do not talk much with a foolish man,
    and do not visit an unintelligent man;
guard yourself from him to escape trouble,
    and you will not be soiled when he shakes himself off;
avoid him and you will find rest,
    and you will never be wearied by his madness.
¹⁴ What is heavier than lead?
    And what is its name except “Fool”?
¹⁵ Sand, salt, and a piece of iron
    are easier to bear than a stupid man.
