Text Snapshot

The Rambam opens his Mishneh Torah by defining the Oral Law: "התורה בכתב, והמצוה – היא פירושה. וצונו לעשות התורה על פי המצוה. והמצוה הזאת היא הנקראת תורה שבעל פה."¹ He then states the original prohibition against writing it: "התורה – משה רבינו כתבה כולה קודם שימות... אבל המצוה – שהיא פירוש התורה – לא כתבה."² Later, he explains Rabbi Yehudah HaNasi's hora'as sha'ah (emergency decree) to codify the Mishnah due to "צרות המתחדשות"³ and extends this rationale to his own work due to subsequent "צרות יתירות".⁴ The nuance of "המצוה" as the explanation (פירושה) of "התורה" highlights the inseparable nature of Written and Oral Law.

Readings

Ra'avad

The Ra'avad⁵ critically questions Rambam's methodology of omitting sources, stating that it deprives judges of the ability to re-evaluate rulings based on differing authorities. His chiddush emphasizes the importance of transparent sourcing for halachic deliberation and judicial review.

Rambam's Introduction to Sefer HaMitzvot

The Rambam himself, in his Introduction to Sefer HaMitzvot,⁶ explains his initial goal of brevity by omitting proofs, and later expressed regret, wishing to add the sources. This reveals his chiddush: a pragmatic prioritization of accessibility and clarity for the masses over exhaustive source citation, driven by the urgency of preserving the entire Oral Law.

Friction

Kushya: How could the Rambam justify codifying the entire Torah Sheba'al Peh, given the explicit prohibition in Gittin 60b ("דברים שבעל פה אי אתה רשאי לאומרם בכתב")? Rabbi Yehudah HaNasi's Mishnah was a rare hora'as sha'ah, yet Rambam's project seems an even greater departure, aiming to be the sole required text. Terutz: The Rambam argues that his era faced even graver "צרות יתירות"⁷ – increased dispersion and dwindling scholarship – necessitating a comprehensive written compendium to prevent the Oral Law's complete loss. This is an extension of R' Yehudah HaNasi's precedent, fulfilling the mandate of "עשו משמרת למשמרתי"⁸ by safeguarding Torah via codification.

Intertext

• Deuteronomy 17:11: "לא תסור מן הדבר אשר יגידו לך ימין ושמאל"⁹ – This foundational verse underpins the authority of the Sanhedrin and, by extension, the universally binding nature of all Talmudic enactments, distinguishing them from post-Talmudic rulings.
• Gittin 60b: "דברים שבכתב אי אתה רשאי לאומרם על פה, דברים שבעל פה אי אתה רשאי לאומרם בכתב"¹⁰ – The classic source for the prohibition against writing down the Oral Law, the very challenge Rambam addresses.

Psak/Practice

The Rambam's introduction establishes a critical meta-halachic principle: all matters in the Babylonian Talmud are universally binding ("חייבים כל ישראל ללכת אחריהם"),¹¹ whereas post-Talmudic enactments are generally binding only locally where accepted. This distinction is foundational for later halachic codification and practice.

Takeaway

The Mishneh Torah is a monumental act of preservation, born from historical necessity, ensuring the continuity and accessibility of the Oral Law as a unified, authoritative system despite its initial oral nature.
