Proverbs 12:1 - Joseph Benson’s Commentary on the Old and New Testaments

Whose loveth instruction Admonition, or reproof, (as appears from the next clause,) which is a singular means of gaining true wisdom; loveth knowledge Shows that he is a true lover of it, because he is willing to purchase it upon such unwelcome terms, as reproofs are generally thought to be. But he that hateth reproof Who cannot endure to be told of, and reproved for, his faults; is brutish Discovers himself to be a most foolish and stupid creature, because he is an enemy to himself, and to his own happiness.
