Maimonides organised the Mishneh Torah as fourteen books, a number remembered in the work's traditional byname Yad ha-Chazakah, the strong hand, since the Hebrew letters for fourteen spell yad, hand. The architecture was itself a statement. Where the Talmud preserves law embedded in winding argument, Maimonides re-sorted the entire tradition into a rational order of his own devising. The first book, Sefer ha-Madda, the Book of Knowledge, opens not with ritual detail but with the existence and unity of God, the ethics of character, the laws of Torah study and the prohibition of idolatry, planting philosophy at the foundation of the code.
From there the books proceed through love of God expressed in daily practice, the seasons and festivals, women and marriage, holiness in food and forbidden relations, vows, agriculture, the Temple service, purity, damages, acquisitions, civil judgments, and finally kings and wars, closing with the laws of the messianic age. Nothing was omitted for being inapplicable: sacrifices, purity and the Sanhedrin are codified as fully as Sabbath and prayer, because the code was written for all of the law, in exile and after it. Each book divides into topical treatises, and each treatise into numbered chapters and paragraphs, a reference system so clean that it remains the standard way of citing him.
