1. The Torah – Foundation of Revelation
Judaism distinguishes two dimensions of the Torah transmitted to Moses at Sinai. The Written Torah (Torah she-bikhtav) refers to the Pentateuch, the five books: Bereshit (Genesis), Shemot (Exodus), Vayikra (Leviticus), Bamidbar (Numbers), and Devarim (Deuteronomy). This collection is also called the Chumash.
The Oral Torah (Torah she-be'al peh) encompasses the Mishnah, the Talmud, the Midrash, and all rabbinic commentary. It constitutes the essential lens through which the Written Torah is interpreted.
Without it, many mitzvot would remain inapplicable: for example, the Torah commands to "bind a sign on your hand" without specifying what it is; it is the Oral Torah that describes the tefillin.
The principle of Torah mi-Sinai affirms that the Torah, both written and oral, was revealed by God to Moses at Mount Sinai. This principle establishes the divine authority of the Torah and its immutable character in Orthodox Judaism.
Tradition counts 613 mitzvot (taryag): 248 positive commandments and 365 prohibitions. This enumeration, mentioned in the Talmud (Makkot 23b), was systematized by Maimonides in the Sefer haMitzvot.
The Sefer Torah and Public Reading
The Sefer Torah is a handwritten parchment scroll, written by a sofer stam (qualified scribe) with special ink and a quill. It contains approximately 304,805 letters, without vowels or cantillation marks. Any uncorrected error renders the scroll passul (invalid). The writing takes one to two years.
The Torah is divided into 54 parashiyot (weekly portions), read on Shabbat. The annual cycle concludes and recommences at Simchat Torah. The Torah is also read on Monday, Thursday, Rosh Chodesh, holidays, fast days, Hanukkah, and Purim. According to tradition, Ezra the Scribe established the Monday and Thursday reading.

First aliyah: a Cohen • Second: a Levi
Maftir: the last person called, who reads the final verses and then the haftarah.
Yad: a metal or wooden pointer used to follow the lines without touching the parchment.
2. The Tanakh – The Hebrew Bible
TaNaKh is the acronym for Torah (Pentateuch), Nevi'im (Prophets), and Ketuvim (Writings/Hagiographa). The Jewish canon traditionally comprises 24 books, as certain texts are grouped together: Samuel, Kings, and Chronicles each form a single book, and the Twelve Minor Prophets are gathered in one volume (Tre Asar).
The Nevi'im Rishonim (Former Prophets: Joshua, Judges, Samuel, Kings) are historical books. The Nevi'im Acharonim (Latter Prophets: Isaiah, Jeremiah, Ezekiel, and the Twelve) are prophetic books.
The Book of Daniel is classified in the Ketuvim because, according to rabbinic tradition, Daniel possessed ruach hakodesh (divine inspiration) but did not hold the status of a prophet in the strict sense.
The last book of the Tanakh in the Jewish order is Divrei haYamim (Chronicles), which closes with the edict of Cyrus authorizing the return of the exiles – a call to hope and return to the Land of Israel.
The Five Megillot and Their Festivals
- Shir haShirim (Song of Songs) → Pesach
- Ruth → Shavuot
- Eicha (Lamentations) → Tisha B'Av
- Kohelet (Ecclesiastes) → Sukkot
- Esther → Purim
The haftarah is a passage from the Nevi'im read after the parashah, whose theme is connected to it. It is read on Shabbat, holidays, and Tisha B'Av.
3. The Midrash – Textual Interpretation
Midrash is a method of rabbinic interpretation of the biblical text. Two types are distinguished: Midrash Halakha, which derives practical laws from verses (e.g., the Mekhilta on Exodus, the Sifra on Leviticus), and Midrash Aggadah, which offers narratives, parables, and moral teachings (e.g., Bereishit Rabbah, compiled in the Land of Israel in the 5th century).
Midrash Aggadah has no binding legal authority, but it profoundly shapes the Jewish worldview.
The central pedagogical tool of Midrash is the mashal (parable), often introduced by "What is this like? A king who..." It comprises the mashal and the nimshal (its application).
The Four Levels of Interpretation – PaRDeS
The 13 middot of Rabbi Yishmael are the hermeneutical rules for deriving laws from the Torah. Among the best known: kal va-chomer (a fortiori), gezerah shavah (verbal analogy), klal u-frat (general/particular).
4. The Mishnah and the Talmud
The Mishnah
The Mishnah is the first written compilation of the Oral Law, compiled by Rabbi Yehudah haNasi around 200 CE. Facing Roman persecutions and the risk of forgetting, he relied on the principle et la'asot laShem (it is time to act for God) to commit it to writing.
It is written in Mishnaic Hebrew and comprises 6 orders (sedarim) and 63 tractates.
The Six Orders of the Mishnah (mnemonic: ZeMaN NaQaT)
The Sages of the Mishnah are the Tannaim (1st–3rd century). The Tosefta ("supplement"), attributed to Rabbi Chiya and Rabbi Oshaya, gathers baraitot (Tannaitic teachings not included in the Mishnah) and complements or nuances its teachings.
The Gemara and the Talmud
The Gemara is the commentary and development of the Mishnah by the Amoraim (3rd–6th century), written primarily in Aramaic. Mishnah + Gemara = Talmud.
An Amora cannot contradict a Tanna without support from another Tannaitic source.
Two versions of the Talmud exist: the Jerusalem Talmud (Yerushalmi, completed around the 4th century) and the Babylonian Talmud (Bavli, completed around the 6th century). The Bavli holds authority in normative halakha.
The orders Zera'im (except Berakhot) and Tohorot (except Niddah) have no Babylonian Gemara, as those laws had no practical application outside the Land of Israel or without the Temple.
The unit of Talmudic discussion is the sugya: citation of the Mishnah, question (kushya), attempts at resolution (terutzim), proofs and counter-proofs. When a question remains unresolved, it is called teiku – traditionally interpreted as "the prophet Elijah will resolve the questions at the end of days."
Approximately one-third of the Bavli is aggadah (narratives, parables, ethics), interwoven with halakha.
The Talmud page (Vilna edition, 1880-86): in the center, Mishnah and Gemara. Inner column: Rashi. Outer column: Tosafot. In the margins: Ein Mishpat, Torah Or, etc.
Daf Yomi: a program of studying one page per day, established by Rav Meir Shapiro of Lublin in 1923. Complete cycle: approximately 2,711 pages over 7 and a half years.
5. The Great Commentators
Rashi (Rabbi Shlomo ben Yitzchak, Troyes, ~1040–1105) is the foundational commentator on the Torah and the Talmud. His commentaries combine the literal meaning (pshat) and midrash, making the text accessible.
The Tosafot are medieval commentaries on the Talmud written by his students and descendants, who deepen and sometimes challenge Rashi's interpretations.
6. The Zohar – Jewish Mysticism
The Zohar is the central text of Kabbalah. Tradition attributes it to Rabbi Shimon bar Yochai (2nd century), but academic research (Gershom Scholem) identifies Moses de León (Spanish kabbalist, 13th century) as its primary author. It is written in artificial Aramaic.
The Zohar describes the ten Sefirot, divine attributes or emanations forming a dynamic system: Keter, Chokhmah, Binah, Chesed, Gevurah, Tiferet, Netzach, Hod, Yesod, and Malkhut.
Its liturgical influence is considerable: Lecha Dodi, the Tikkun Chatzot, the Tikkun Leil Shavuot, and the leshem yichud formulas derive from it.
Lurianic Kabbalah (Rabbi Yitzchak Luria, 16th century, Safed) interprets and systematizes the Zohar, developing the concepts of Tzimtzum (divine contraction), Shevirat haKelim (shattering of the vessels), and Tikkun (repair).
Tradition recommended not studying Kabbalah before age 40 and without a solid foundation in Torah and Talmud. Hasidism relaxed this restriction.
7. The Codes of Law (Halakha)
Halakha (literally "the path") refers to the complete body of religious rules of conduct. A distinction is made between de'oraita laws (of biblical origin) and derabanan laws (of rabbinic origin).
The Four Great Halakhic Codes
- Mishneh Torah – Maimonides (Rambam), 12th century: systematic presentation of all Jewish law.
- Arba'ah Turim – Rabbi Yaakov ben Asher, 14th century.
- Shulchan Arukh – Rabbi Yosef Karo, 16th century (Sephardic tradition).
- Mappah – Rabbi Moshe Isserles (Rema), 16th century: Ashkenazi glosses on the Shulchan Arukh.
Orach Chaim (daily life, prayers, Shabbat, holidays), Yoreh De'ah (kashrut, niddah, mourning, conversions), Even haEzer (marriage and divorce), and Choshen Mishpat (civil and judicial law).
The Mishnah Berurah by the Chofetz Chaim (1839-1933) has become the dominant Ashkenazi reference on the Orach Chaim section.
The mara de-atra (master of the place) is the local rabbi whose authority prevails in his community. Even in the presence of universal codes, he may rule according to local circumstances and established customs. There is no "pope" in Judaism.
8. She'alot uTeshuvot (SHuT) – Responsa
A responsum (teshuvah) is a written answer from a rabbinic authority to a concrete halakhic question. Unlike codes that systematize the law in a general way, responsa address specific cases and allow halakha to adapt to new situations (technology, medicine, etc.).
The oldest preserved responsa are the Teshuvot haGeonim (7th–11th century, Babylonia). Among the major modern collections: the Igrot Moshe by Rav Moshe Feinstein (Ashkenazi reference, 20th century) and the Yabia Omer by Rav Ovadia Yosef (Sephardic reference, 20th century).
A responsum is binding only on the person or community that posed the question. The system is decentralized: there is no universal rabbinic authority, and contemporary decisors may hold divergent opinions.
For modern questions (electricity on Shabbat, IVF, artificial intelligence), poskim use analogical reasoning to identify the relevant halakhic category.
