Proverbs 15:12

A scorner is one that not only makes a jest of God and religion, but bids defiance to the methods employed for his conviction and reformation, and, as an evidence of that, 1. He cannot endure the checks of his own conscience, nor will he suffer it to deal plainly with him: He loves not to reprove him (so some read it); he cannot endure to retire into his own heart and commune seriously with that, will not admit of any free thought or fair reasoning with himself, nor let his own heart smite him, if he can help it. That man's case is sad who is afraid of being acquainted and of arguing with himself. 2. He cannot endure the advice and admonitions of his friends: He will not go unto the wise, lest they should give him wise counsel. We ought not only to bid the wise welcome when they come to us, but to go to them, as beggars to the rich man's door for an alms; but this the scorner will not do, for fear of being told of his faults and prevailed upon to reform.

15:12 Mockers cannot become wise because they keep criticism at a distance (cp. 10:17; 13:1, 10).
