Proverbs of a 36 yr old man
A truly wise person uses few words and a person of understanding has a calm spirit. You will say the wrong thing if you talk too much. Be sensible and watch what you say.
Words are powerful. It is better to say nothing, than to speak evil words. The heart of the righteous ponders how to answer, but the mouth of the wicked blurts out evil.
