The Bible gives the reason for this: “In order that he may learn to fear Jehovah his God so as to keep all the words of this law and these regulations by doing them; that his heart may not exalt itself above his brothers and that he may not turn aside from the commandment to the right or to the left. ”
המקרא גם מסביר מדוע: ” למען ילמד ליראה את יהוה אלוהיו לשמור את כל דברי התורה הזאת ואת החוקים האלה לעשותם.
