Proverbs 9:7 - 9:9

He who disciplines a scoffer receives disgrace for himself,

And he who reproves a wicked man receives injury for himself.

Do not reprove a scoffer, lest he hate you,

Reprove a wise man and he will love you.

Give knowledge to a wise man and he will be still wiser,

Make a righteous man know it and he will increase his learning.
