Go from the presence of a foolish man, in whom thou perceivest not the lips of knowledge.

A wise son maketh a glad father; but a foolish man despiseth his mother.

There is costly store and oil in the dwelling of a wise man; but a foolish man swalloweth it up.

Speak not in the ears of a foolish man, for he will despise the wisdom of thy words.
