Proverbs 9:7-9

⁷He that instructeth a scorner getteth to himself shame; and he that reproveth a wicked man getteth to himself a blot.

⁸Reprove not a scorner, lest he hate thee; reprove a wise man, and he will love thee.

⁹Impart to a wise man, and he will become yet wiser; teach a righteous man, and he will increase learning.
