DEUT902 The King of Israel shall write a sefer Torah in addition to the one that every Jew has a mitzvah to write. The King is the most independent and powerful person in the land. No one can tell him what to do. With one word he can decree death on whomever he wishes, so it is important that he be restrained and in control of himself at all times. He must keep a tight rein on his evil inclination, and be reminded to incline his heart to his Maker at all times. Therefore, a sefer Torah must be with him at all times, and it should never be out of his sight.
