Proverbs 10:20 - Joseph Benson’s Commentary on the Old and New Testaments

The tongue of the just is as choice silver Of great worth and use, bringing credit to himself, and great benefit to others; the heart of the wicked is little worth And consequently his tongue, which speaketh out of the abundance of the heart, Matthew 12:34. The lips of the righteous feed many By their wise and pious discourses, counsels, and comforts, which are so many evidences of their wisdom: but fools die for want of wisdom They have not wisdom to preserve themselves, much less to feed others.
