Sirach 20:18-20

New Revised Standard Version, Anglicised

¹⁸ A slip on the pavement is better than a slip of the tongue;
    the downfall of the wicked will occur just as speedily.
¹⁹ A coarse person is like an inappropriate story
    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 the proper time.
