'Foolish Man' in the Bible

“For anger slays the foolish man,And jealousy kills the simple.

Arise, O God, and plead Your own cause;Remember how the foolish man reproaches You all day long.

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

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

When a wise man has a controversy with a foolish man,The foolish man either rages or laughs, and there is no rest.

A wise man’s heart directs him toward the right, but the foolish man’s heart directs him toward the left.
