th  Mitzvah "and now write for you this song" Deuteronomy 31:19, Maimonides says, "By this injunction, we are commanded that every person among us is to have a scroll of the Torah for himself.....If he writes it with his own hand, Scripture considers it as if he had received it from Mount Sinai. If he cannot write it himself, he is obliged to purchase one, or to hire a scribe who will write it for him".
