Proverbs 29:9

"If a wise man hath a controversy with a foolish man, Whether he be angry or laugh, there will be no rest."

"The subject of the second line is uncertain; but the proverb seems to be a warning against a wise man's going to law with a fool."[10] "When an intelligent man brings a lawsuit against a fool, the fool only laughs and becomes loud and abusive."[11] "If a wise man has an argument with a fool, the fool only rages and laughs, and there is no quiet."[12] The RSV is superior here.
