Proverbs 9:7 in the World English Bible
One who corrects a mocker invites insult. One who reproves a wicked man invites abuse.
Context
6 Forsake the foolish, and live; and go in the way of understanding.
7 He that reproveth a scorner getteth to himself shame: and he that rebuketh a wicked man getteth himself a blot.
8 Reprove not a scorner, lest he hate thee: rebuke a wise man, and he will love thee.
