Proverbs 13:15 - Joseph Benson’s Commentary on the Old and New Testaments

Good understanding Discovering itself by a man's holy and righteous practices; giveth favour Maketh a man acceptable both to God and men; but the way of transgressors Their conduct, or manner of conversation is hard; Hebrew, איתן, rough, as this very word is rendered Deuteronomy 21:4; it is offensive to God and men, as rough ways are to travellers; fierce, intractable, and incorrigible. Bishop Patrick interprets the verse thus: “If a man have understanding enough to be thoroughly good, he will find things favourable to his honest desires; but they that take evil courses meet with great difficulties, and are forced to go backward and forward, and wind and turn every way, to bring about their ends, or save themselves perhaps from ruin.”
