Wisdom of Ben Sira 20:18-20

New Catholic Bible

¹⁸ A slip on the pavement is better than a slip of the tongue;
    the downfall of the wicked will come just as quickly.
¹⁹ A coarse person is like an indiscreet story
    that is continually on the lips of the ignorant.
²⁰ A proverb is rejected when it comes from the lips of a fool
    since he does not utter it at the proper time.
