Wisdom of Ben Sira 22:12-14

New Catholic Bible

¹² Mourning for the dead lasts seven days,
    but for the foolish and the ungodly it lasts all the days of their life.
¹³ Do not speak often with a fool,
    or visit a stupid person.
[For since he is without sense,
    he will despise everything about you.]^[a]
Beware of him or you may find yourself in trouble
    and be splattered by contact with him.
Avoid him and you will have peace of mind
    and not be exasperated by his lack of sense.
¹⁴ What is heavier than lead,
    and what is its name but “Fool”?
