Proverbs 10:8

A wise man obeys instructions. He tries to learn from other people.

If you give instructions to a fool, he does not listen. By ‘fool’, Solomon means a person who refuses to obey God.

A fool only thinks his own thoughts. He only hears his own words. He only does what he wants to do. A fool is proud. He thinks that he is wiser than other people. He thinks that he knows better than God. He trusts only in himself.
