Sirach 22:13-15

New Revised Standard Version Catholic Edition

¹³ Do not talk much with a senseless person
    or visit an unintelligent person.^[a]
Stay clear of him, or you may have trouble,
    and be spattered when he shakes himself off.
Avoid him and you will find rest,
    and you will never be wearied by his lack of sense.
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 person.
