Ecclesiastes 7:20-23

²⁰For there is not a righteous man in the earth, Who will do good, and not sin.

²¹Also take no heed To all the words which ungodly men shall speak; Lest thou hear thy servant cursing thee.

²²For many times he shall trespass against thee, And repeatedly shall he afflict thy heart; For thus also hast thou cursed others.

²³All these things have I proved in wisdom: I said, I will be wise; but it was far from me.
