Proverbs 17:7 - Joseph Benson’s Commentary on the Old and New Testaments

Excellent speech Either, 1st, Discourse concerning difficult, high, and excellent things, far above his capacity: or, 2d, Lofty, eloquent speech, which fools often affect: or, 3d, Virtuous and godly discourse; becometh not a fool Either one properly so called, or, as the word fool is most commonly used in this book, a wicked man, whose actions give the lie to his expressions.
