Ecclesiastes 7:21-23

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 thine 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.
