The commandments are the reference points of Jewish existence, the fulfillment of which, in fact, forms the way of life of a believing Jew. Therefore, it is so important to determine what exactly is included in the concept of commandments. According to the chain of oral tradition (see Babylonian Talmud, Makot, 23b), we have been given knowledge about their number, but neither the Tanakh nor the Mishnah or Talmud gives a list of them. Several versions of such a list have reached our time, but all of them were surpassed by the popularity and breadth of distribution of the "Book of Commandments" of Rambam. In it, he sets out both the principles he laid down as the basis for compiling the list, and the wording of the commandments themselves.Written by Rambam as a separate work, the Book of Commandments is essentially an introduction to his epochal code of the Mishneh Torah and is therefore given at the beginning of all its editions.
