Proverbs 17:7

Solomon uses humour here. A fool (an evil person) should be careful about his words. His words will cause trouble. Instead, he should say nothing. Certainly, he should not try to speak in a clever way. (Of course, a fool would not obey Solomon’s advice.)

However, some things are much worse than a fool who tries to impress people with his proud words. For example, people will not respect a ruler who lies.
