From A Particular Baptist:

He, that being often reproved hardeneth his neck, shall suddenly be destroyed, and that without remedy.   Proverbs 29:1

A STRONGER INDICATION OF A mind unreconciled to God can hardly be conceived than the unwillingness to receive reproof. The humble man is always thankful for admonition administered in the spirit of meekness and prompted by a sincere desire for the welfare of the offender; while the haughty sinner, whose ways are always right in his own eyes, indignantly rejects it. Hence the reasonable precaution which our Saviour addressed to His disciples: “Give not that which is holy unto dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you” (Matthew 7:6).
