Ecclesiastes 7:19-22 - Wisdom Is Valuable, But No One Is Completely Righteous
19 Wisdom strengthens the wise more than ten mighty men who are in the city. 20 For surely there is not a just man upon earth that in doing good does not sin.
21 Also do not take to heart all the words that are spoken lest thou hear thy slave speak evil of thee: 22 For thine own heart knows that thou thyself likewise hast spoken evil of others many times.
