Ecclesiastes 7:19-22 - Wisdom Is Valuable, But No One Is Completely Righteous
19 Wisdom giveth more courage unto the wise, than ten mighty men of the city. 20 For there is not one just upon earth, that doth good, and sinneth not.
21 Take not heed unto every word that is spoken, lest thou hear thy servant curse thee: 22 For thine own heart knoweth, that thou thyself also hast oft times spoken evil by other men.
