The Six Orders of the Mishnah: Judaism's Legal Foundation

The Great Organizing Act

Around the year 200 CE, Rabbi Yehuda HaNasi (Judah the Prince) accomplished something extraordinary. He took the vast, sprawling body of Jewish oral law — centuries of legal rulings, debates, customs, and interpretations passed down by word of mouth — and organized it into a single, structured work.

He called it the Mishnah — from the Hebrew root sh-n-h, meaning “to repeat” or “to study by repetition.” It became the foundation of all subsequent Jewish law, the skeleton upon which the Talmud would be built, and one of the most influential legal documents in human history.

The Mishnah is organized into six orders (sedarim), each covering a major domain of Jewish life. Together, they are sometimes called by the acronym Shas — short for shisha sedarim (six orders). Here they are.

1. Zeraim (Seeds) — Agriculture and Blessings

The first order deals with agriculture and blessings — how human beings relate to the land and to God through food.

Key tractates:

• Berakhot (Blessings): Ironically placed in the agricultural order, this tractate covers prayer times, the Shema, the Amidah, and blessings over food. It is the gateway to the entire Talmud and one of the most studied tractates.
• Peah (Corners): Laws of leaving field corners for the poor — the Torah’s built-in welfare system.
• Demai (Doubtfully Tithed Produce): What to do when you’re unsure whether produce has been properly tithed.
• Kilayim (Mixed Species): Prohibition against mixing certain plant species, animal breeds, and fabric types.
• Shevi’it (Seventh Year): Sabbatical year laws — letting the land rest every seven years.
• Terumot and Ma’asrot (Tithes): The complex system of agricultural contributions to priests, Levites, and the poor.

Zeraim reveals something important: Judaism begins with the earth. Before discussing holidays or Temple rituals, it addresses the fundamental human relationship with the land that sustains life.

2. Moed (Festivals) — Sacred Time

The second order covers Shabbat, holidays, and sacred time — the rhythm of the Jewish year.

Key tractates:

• Shabbat: Laws of the Sabbath, including the 39 prohibited categories of labor. Also contains the Hanukkah laws.
• Eruvin: The laws of creating shared domains for Shabbat carrying — the eruv.
• Pesachim: Passover laws, chametz removal, the Paschal sacrifice, the seder.
• Yoma: Yom Kippur — the High Priest’s Temple service, fasting laws.
• Sukkah: Building the sukkah, the four species (lulav, etrog, etc.).
• Beitzah: General festival laws (Yom Tov).
• Rosh Hashanah: New year, shofar, calendar calculation.
• Ta’anit: Fast days and prayers for rain.
• Megillah: Purim and reading the Book of Esther.
• Mo’ed Katan: Intermediate festival days (Chol HaMoed).
• Chagigah: Festival offerings in the Temple.

Moed is where the Jewish calendar receives its legal architecture. Every holiday celebration today — from the Passover seder to Yom Kippur fasting — traces its rules to these tractates.

3. Nashim (Women) — Family Law

The third order addresses marriage, divorce, and family relationships. The name “Nashim” (Women) reflects the patriarchal legal framework of the ancient world, though the tractates cover obligations of both parties.

Key tractates:

• Yevamot: Levirate marriage (the obligation of a brother to marry his deceased brother’s childless widow).
• Ketubot: The marriage contract, marital obligations, and financial arrangements.
• Nedarim: Vows and their annulment.
• Nazir: The Nazirite vow — voluntarily abstaining from wine, haircuts, and corpse contact.
• Sotah: The suspected adulteress — a procedure largely theoretical by the time of the Mishnah.
• Gittin: Divorce law and the requirements of a valid get (divorce document).
• Kiddushin: Betrothal — how marriage is legally established.

These tractates shaped Jewish family life for two millennia. The ketubot (marriage contracts) still used at Jewish weddings today derive directly from Tractate Ketubot’s specifications.

4. Nezikin (Damages) — Civil and Criminal Law

The fourth order is the legal code — covering property, commerce, courts, and punishment. It is the most “secular” in subject matter and the most directly relevant to daily life.

Key tractates:

• Bava Kamma (First Gate): Damages, theft, robbery, personal injury.
• Bava Metzia (Middle Gate): Lost objects, loans, rentals, employer-employee relations. Contains the famous Oven of Akhnai story.
• Bava Batra (Last Gate): Property law, inheritance, sales, partnerships.
• Sanhedrin: Courts, judicial procedure, capital punishment, theological discussions about the World to Come.
• Makkot: Corporal punishment (lashes), cities of refuge.
• Shevuot: Oaths in legal contexts.
• Eduyot: Collected testimonies of major legal opinions.
• Avodah Zarah: Laws concerning idolatry and relations with non-Jews.
• Avot (Ethics of the Fathers): The only purely ethical tractate — no laws, just wisdom. The most widely read tractate of the entire Mishnah.
• Horayot: Erroneous judicial decisions.

Pirkei Avot (Ethics of the Fathers) stands out. It contains no legal rulings — only ethical maxims from generations of sages. “If I am not for myself, who will be for me? But if I am only for myself, what am I?” (Hillel, Avot 1:14). It is customary to study Avot on Shabbat afternoons between Passover and Rosh Hashanah.

5. Kodashim (Holy Things) — Temple and Sacrifice

The fifth order covers Temple rituals, sacrifices, and dietary laws — much of it theoretical after the Temple’s destruction in 70 CE.

Key tractates:

• Zevachim: Animal sacrifices — types, procedures, disqualifications.
• Menachot: Meal offerings, tzitzit, tefillin.
• Chullin: Ritual slaughter for ordinary (non-sacrificial) consumption — the foundation of kashrut laws.
• Bekhorot: Firstborn animals and their sanctity.
• Arakhin: Valuations — pledging one’s monetary worth to the Temple.
• Temurah: Substituting one sacrificial animal for another.
• Keritot: Sins punishable by divine excision (karet).
• Me’ilah: Misuse of sacred property.
• Tamid: The daily Temple service.
• Middot: Measurements and architecture of the Temple — a blueprint in words.

Why study the laws of a Temple that no longer stands? The traditional answer: because the study itself is considered equivalent to performing the service, and because these laws will apply again when the Temple is rebuilt.

6. Taharot (Purities) — Ritual Purity

The sixth and final order deals with ritual purity and impurity — a complex system governing who and what may enter the Temple or participate in certain rituals.

Key tractates:

• Kelim (Vessels): The longest tractate in the Mishnah (30 chapters) — which vessels can become ritually impure and how.
• Ohalot (Tents): Impurity transmitted under a roof where a corpse is present.
• Nega’im (Afflictions): Biblical skin diseases (often mistranslated as “leprosy”) and their diagnosis.
• Parah (Red Heifer): The mysterious red heifer purification ritual.
• Mikva’ot (Ritual Baths): Requirements for valid mikvaot — still practically relevant today.
• Niddah: Laws of menstrual impurity and family purity — the most practically observed tractate in this order.

Taharot is the least studied order in modern times because most of its laws are inapplicable without the Temple. The exception is Niddah, whose laws continue to govern family purity practices in observant communities.

The Whole of Jewish Life

Together, the six orders cover every aspect of human existence: work and rest, eating and fasting, marriage and divorce, property and commerce, worship and purity, birth and death. The Mishnah’s ambition is total — no domain of life falls outside the reach of Jewish law.

The mnemonic traditionally used to remember the six orders is: “Zman Nakat” (זמן נקט) — formed from the first letters of Zeraim, Moed, Nashim, Nezikin, Kodashim, and Taharot.

Rabbi Yehuda HaNasi’s organizational genius created a framework that has lasted nearly two thousand years. When the Talmud was compiled — the Babylonian Talmud (around 500 CE) and the Jerusalem Talmud (around 400 CE) — it followed the Mishnah’s structure exactly. Every page of Talmud begins with a Mishnah passage and then explores, debates, and expands it. The Mishnah is the skeleton. Everything else is the body built around it.
