'Foolish Man' in the Bible

Wise men lay up knowledge, but the mouth of a foolish man is a present destruction.

He who troubles his own house shall inherit the wind. And a foolish man shall be servant to a wise man of heart.

Go into the presence of a foolish man, and thou shall not perceive the lips of knowledge.

A wise son makes a glad father, but a foolish man despises his mother.

There is precious treasure and oil in the dwelling of a wise man, but a foolish man swallows it up.

If a wise man has a controversy with a foolish man, whether he be angry or laugh, there will be no rest.
