Proverbs 27:22 - Joseph Benson’s Commentary on the Old and New Testaments

Though thou shouldest bray, &c. “The folly and wickedness of some men are so incurable, that though unto reproofs, and chidings, and threatenings, you should add stripes and blows, they would not grow a whit the wiser or better for it.” Not natural, but moral and wilful fools are here intended, who, by long continuance in sin, are hardened and stupified, and so are become incorrigible under all the means of amendment.
