Sirach 20:18-20

Revised Standard Version Catholic Edition

¹⁸ A slip on the pavement is better than a slip of the tongue;
    so the downfall of the wicked will occur speedily.
¹⁹ An ungracious man is like a story told at the wrong time,
    which is continually on the lips of the ignorant.
²⁰ A proverb from a fool’s lips will be rejected,
    for he does not tell it at its proper time.
