19Sin shall not fail in much speaking; but he that measureth his lips, is most prudent. (Sin shall abound with much speaking; but he who ruleth his lips, is most prudent.)
20Chosen silver is the tongue of a just man; the heart of wicked men is for nought. (Choice silver is like the tongue of a righteous person; but the hearts of the wicked be worth nothing.)
