Proverbs 9:7-9

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[a] to a wise man, and he will be still wiser;

    teach a righteous man, and he will increase in learning.
