Ecclesiasticus 41:15
14. My children, keep discipline in peace: for wisdom that is hid, and a treasure that is not seen, what profit is in them both?15. A man that hideth his foolishness is better than a man that hideth his wisdom.16. Therefore be shamefaced according to my word: for it is not good to retain all shamefacedness; neither is it altogether approved in every thing.
