Proverbs 9:7-9

¶He who corrects and instructs a scoffer gets dishonor for himself, And he who rebukes a wicked man gets insults for himself. Do not correct a scoffer [who foolishly ridicules and takes no responsibility for his error] or he will hate you; Correct a wise man [who learns from his error], and he will love you. [Ps 141:5] Give instruction to a wise man and he will become even wiser; Teach a righteous man and he will increase his learning.
