Layers of the Talmud: Understanding Gemara Composition

The Mishnah is a collection of teachings from the Tannaim (sages of the early rabbinic period) and is the foundational text upon which the Talmud is built. It was compiled in the Land of Israel by Rabbi Yehuda HaNasi and is divided into six orders: Zeraim (agriculture and blessings), Moed (festivals), Nashim (family law), Nezikin (damages and civil law), Kodashim (sacrifices), and Taharot (purity).

The Talmud is structured around the Mishnah—each sugya (Talmudic discussion) typically begins with a question or exploration of a Mishnah. In fact, the Talmud is, among other things, a highly detailed commentary on the Mishnah. When there is a contradiction between the Mishnah and another source in the Talmud, the Mishnah takes precedence.

You can usually recognize a Mishnah within the Talmud because:

• It is written in Hebrew (unlike most of the Talmud, which is in Aramaic).
  
• It is sometimes introduced with the word “Tnan“ (“we learned in a Mishnah”).

Baraitot (singular: Baraita) are teachings from the Tannaim that were not included in the Mishnah. Many appear throughout the Talmud as well as in the Tosefta, a companion work to the Mishnah that includes additional Tannaitic teachings. The Tosefta was compiled by Rabbi Chiya and Rabbi Oshaya, students of Rabbi Yehuda HaNasi.

The word Baraita means “external” in Aramaic, referring to material that remained outside of the official Mishnah compilation.

In cases of contradiction:

• The Mishnah takes precedence over a Baraita.
• A Baraita takes precedence over an Amoraic statement.

Baraitot can also be identified by:

• Their Hebrew language.
• Introductory phrases such as “Detanu Rabbanan“ (“the Rabbis taught”) or “Detanya“ (“it was taught in a Baraita”).

Midreshei Halacha are legal interpretations of biblical verses from the Tannaitic period. These midrashim derive laws directly from Scripture.

Major collections of Midreshei Halacha include:

• Mekhilta – on the Book of Exodus
• Sifra – on Leviticus
• Sifrei – on Numbers and Deuteronomy

These works reflect the methodologies of different schools of thought, such as those of Rabbi Yishmael and Rabbi Akiva, each with distinct interpretive styles. There is no Midrash Halacha on the Book of Genesis, likely because it contains mostly narratives rather than legal material.

Like the Mishnah and Baraita, these midrashim are written in Hebrew, since they were composed in the Land of Israel during the Tannaitic period.

A typical structure of a Midrash Halacha includes:

• A biblical verse.
• A question based on the verse.
• A resolution of the question that reveals a halachic insight.

Example from Sifrei (Bemidbar 5:1-2):

Verse: “And the Lord spoke to Moses, saying: Command the children of Israel that they send out of the camp every leper (metzora) and everyone with a discharge (zav), and everyone that had contact with a dead body (tamei met).”
Question: Why was this section stated?
Answer: This is the exhortation that the unclean not enter the sanctuary in a state of uncleanliness.

The majority of the Talmud is composed of the teachings and discussions of the Amoraim, the sages who lived after the Tannaim. They ask questions, offer answers, develop legal innovations, and engage in discussions with each other.

Amoraic teachings may appear:

• With attribution, e.g., “Amar Rava” (“Rava said”).
• Anonymously, e.g., “Amar Mar” (“The Master said”), often representing the voice of the Talmud’s anonymous redactor—Stam HaGemara.

One common example of a question by the Stam follows the opening Mishnah in Berakhot:

“Tana heikha kai dekatani me’eimatai?”
“Where is the Tana standing when he teaches ‘From when [do we recite the Shema]?’”

The Amoraim continue the chain of tradition by engaging with the earlier texts and generating new insights. Their statements are written in Aramaic.

• In Babylonian Talmud, Amoraim are referred to as “Rav”.
  
• In the Jerusalem Talmud, they are called “Rabbi”—as were the Tannaim.

Aggadot (singular: Aggadah) are non-legal passages in the Talmud. These include:

• Stories
• Biblical interpretations
• Medical advice
• Wise sayings and ethical teachings

Aggadah covers a wide range of topics—from ethics, faith, and how to live a meaningful life, to health and personal development. While they are not used to determine legal rulings, Aggadot play an important role in the spiritual and moral dimensions of Torah study.

Aggadic passages may appear in Hebrew or Aramaic, depending on their origin and time period.

Here are some general rules of thumb:

• Language:
  • Hebrew = likely a Tannaitic source (Mishnah, Baraita, or Midrash Halacha).
  • Aramaic = typically from the Amoraic period.
• Chronology:
  • A sage cannot argue with one from an earlier generation. So for example:
  • A Tanna may dispute another Tanna.
  • An Amora cannot argue with a Tanna.
  • If a second opinion directly contradicts a Tannaitic view, it is probably also from the Tannaitic period.
• Titles:
  • “Rav” indicates a Babylonian Amora.
  • “Rabbi” may refer to either a Tanna or an Eretz Yisrael Amora.
    Since the Talmud Bavli contains far more Tannaitic material, if unsure, it’s usually a safe guess that “Rabbi” refers to a Tanna.
• Introductory Phrases:
  • Tnan – תנן  – Mishnah
  • Detanu Rabbanan, Detanya דתנו רבנן, דתניא– Baraita or Midrash Halacha
  • Amar Mar, De’itmar אמר מר, דאיתמר– Amoraic statements
