7 Whoever corrects a scoffer gets himself abuse,
and he who reproves a wicked man incurs injury.
8 Do not reprove a scoffer, or he will hate you;
reprove a wise man, and he will love you.
9 Give instruction  to a wise man, and he will be still wiser;
teach a righteous man, and he will increase in learning. (ESV)
