Provérbios 10

Provérbios 10:19

If, for the sake of silence, we ought sometimes not to speak what is good, then even more are we obliged to avoid all evil talk, for fear of the punishment due to sin. Therefore, frequent leave to talk is not to be granted to those who are advanced in perfection, even if the subject is good and holy and edifying. Because it is written, "In much talk you shall not avoid sin," and elsewhere, "Life and death are in the power of the tongue." It belongs to the master to speak and teach, and it is the duty of the disciple to hear and obey. — RULE OF ST. BENEDICT 6
