Proverbs 20:3

A wise man tries not to argue. He is polite - see Acts 26:2-3. Sometimes he says nothing, to avoid an argument - see Mark 14:61. But sometimes he must speak, although other people will be angry (Mark 14:62-65). His wisdom will guide him to know what to say.

A fool is evil and he hates wisdom. He loves arguments, because he loves his evil behaviour.
