Literary Sources

Jewish tradition teaches that at Mount Sinai, God gave Moses two simultaneous revelations: the Torah sheb'khtav (Written Torah — the Five Books of Moses) and the Torah sheb'al peh (Oral Torah — the explanatory tradition transmitted verbally from teacher to student). The Written Torah alone is often cryptic; it says "bind [these words] as a sign on your hand" (Deut. 6:8) without explaining exactly how — the Oral Torah explains through the practice of tefillin.

This concept, known as Torah mi-Sinai (Torah from Sinai), is one of Maimonides' 13 Principles of Faith. The entire chain of rabbinic literature — Mishnah, Talmud, Midrash, codes, and responsa — is considered part of this living Oral Torah, continuously unfolding across generations.

The TaNaKH (תַּנַ"ךְ) is the Hebrew Bible — its name is an acronym for its three sections:

The Torah carries the highest legal authority. The Five Megillot (scrolls) within Ketuvim are read publicly on specific occasions:

Midrash (מִדְרָשׁ, from darash — "to seek out, interpret") is the body of rabbinic literature that interprets biblical texts through story, parable (mashal), and allegory. There are two main types:

• Midrash Halacha — legal interpretation (e.g., Mekhilta on Exodus, Sifra on Leviticus)
• Midrash Aggadah — narrative/homiletical interpretation (e.g., Bereishit Rabbah, Midrash Tehillim)

Rabbinic interpretation operates through the PaRDeS framework — four levels of meaning in every biblical text:

After the destruction of the Second Temple (70 CE) and subsequent dispersal, Rabbi Judah HaNasi (Rebbi) recognized that the Oral Torah was in danger of being lost. Around 200 CE, he compiled it into the Mishnah (מִשְׁנָה, "repetition") — the first written codification of Jewish law.

The Mishnah is organized into 6 Orders (Sedarim), containing 63 tractates (masekhtot). A mnemonic: ZeMaN NaQaT:

After the Mishnah was compiled, the rabbinic academies of two centers debated its meaning for centuries. These debates — the Gemara (גְּמָרָא, "completion") — were compiled alongside the Mishnah text to form the Talmud. There are two versions:

A sugya is a unit of Talmudic discussion — typically a Mishnaic passage followed by extended analysis, debates among named sages, proof texts, narratives (aggadah), and practical rulings. Roughly one-third of the Bavli is aggadah (narrative/ethical material), two-thirds halacha (legal discussion).

A famous Talmudic term: Teiku (תֵּיקוּ) — an unresolved dispute. Some interpret it as an acronym: Tishbi yetaretz kushyot u've'ayot ("Elijah the Tishbite will resolve difficulties and questions [in the messianic era]").

The two essential Talmud commentaries appear in every standard printed edition of the Talmud (the Vilna edition, published 1880-86, is the standard):

Halacha (הֲלָכָה, "the path") is the complete body of Jewish religious law — both biblical (de'oraita) and rabbinic (derabanan). Over the centuries, great scholars systematized the Talmud's sprawling discussions into organized legal codes:

The Shulchan Aruch (שֻׁלְחָן עָרוּךְ, "Set Table") has four sections:

She'elot uTeshuvot (שְׁאֵלוֹת וּתְשׁוּבוֹת, "questions and answers") — known as responsa — are written rabbinic answers to specific halachic questions submitted by communities and individuals. They have been written since the Geonic period (7th–11th centuries) and continue today.

Classic responsa collections include: Teshuvot haGeonim (earliest); Rashi and Maimonides' responsa; Igrot Moshe by Rav Moshe Feinstein (20th c. America); Yabia Omer by Rav Ovadia Yosef (20th c. Israel/Sephardi).

Modern responsa address questions unimaginable to the Talmud's authors: organ transplants, in-vitro fertilization, electricity on Shabbat, Holocaust-related halacha, and artificial intelligence.

Jewish mysticism has its own vast literature. The Sefer Yetzirah ("Book of Formation") — one of the oldest Jewish mystical texts — explores the mystical significance of Hebrew letters and the 10 sefirot (divine attributes). The Zohar (זֹהַר, "Splendor"), the foundational Kabbalistic text, was published in 13th-century Spain by Moses de León, who attributed it to the 2nd-century sage Rabbi Shimon bar Yochai.
