Gemara in the context of "Shimon bar Yochai"

The Talmud (/ˈtɑːlmʊd, -məd, ˈtæl-/; Hebrew: תַּלְמוּד‎, romanized: Talmūḏ, 'study' or 'learning') is the central text of Rabbinic Judaism and second in authority only to the Hebrew Bible (Tanakh), the first five books of which form the Torah. It is a primary source of Jewish law (הֲלָכָה, Halakha) and Jewish theology. It consists of the part of the Oral Torah compiled in the Mishnah and its commentaries, the Gemara. It records the teachings, opinions and disagreements of thousands of rabbis and Torah scholars—collectively referred to as Chazal—on a variety of subjects, including Halakha, Jewish ethics, philosophy, customs, history, and folklore among other topics. Until the Haskalah in the 18th and 19th centuries, the Talmud was the centerpiece of Jewish culture in nearly all communities and foundational to "all Jewish thought and aspirations", serving also as "the guide for the daily life" of Jews.

"Talmud" is used interchangeably with "Gemara". The text is made up of 63 tractates, each covering one subject area. The language of the Talmud is Jewish Babylonian Aramaic. Talmudic tradition emerged and was compiled between the destruction of the Second Temple in 70 CE and the Arab conquest in the early seventh century. Traditionally, it is thought that the Talmud itself was compiled by Rav Ashi and Ravina II around 500 CE, although it is more likely that this happened in the middle of the sixth century.

Amoraim (Jewish Babylonian Aramaic: אמוראים [ʔamoraˈʔim], singular Amora אמורא [ʔamoˈra]; "those who say" or "those who speak over the people", or "spokesmen") refers to Jewish scholars of the period from about 200 to 500 CE, who "said" or "told over" the teachings of the Oral Torah. They were primarily located in Babylonia and the Land of Israel. Their legal discussions and debates were eventually codified in the Gemara. The Amoraim followed the Tannaim in the sequence of ancient Jewish scholars. The Tannaim were direct transmitters of uncodified oral tradition; the Amoraim expounded upon and clarified the oral law after its initial codification.

Savora (Hebrew: [savoˈʁa]; Aramaic: סבורא, "a reasoner", plural Savora'im, Sabora'im [savoʁaˈ(ʔ)im], סבוראים) is a term used in Jewish law and history to signify one among the leading rabbis living from the end of period of the Amoraim (around 500 CE) to the beginning of the Geonim (around 600 CE). As a group they are also referred to as the Rabbeinu Sevorai or Rabanan Saborai, and may have played a large role in giving the Talmud its current structure. Modern scholars also use the plural term Stammaim (Hebrew; "closed, vague or unattributed sources") for the authors of unattributed statements in the Gemara.

Moed (Hebrew: מועד, 'Festivals') is the second Order of the Mishnah, the first written recording of the Oral Torah of the Jewish people (also the Tosefta and Talmud). Of the six orders of the Mishna, Moed is the third shortest. The order of Moed consists of 12 tractates:

1. Shabbat or Shabbath (שבת‎) ("Sabbath") deals with the 39 prohibitions of "work" on the Shabbat. 24 chapters.
2. Eruvin (ערובין) ("Mixtures") deals with the Eruv or Sabbath-bound - a category of constructions/delineations that alter the domains of the Sabbath for carrying and travel. 10 chapters.
3. Pesahim (פסחים) ("Passover Festivals") deals with the prescriptions regarding the Passover and the paschal sacrifice. 10 chapters.
4. Shekalim (שקלים) ("Shekels") deals with the collection of the half-Shekel as well as the expenses and expenditure of the Temple. 8 chapters
5. Yoma (יומא) ("The Day")—also called "Kippurim" or "Yom ha-Kippurim" ("Day of Atonement")—deals with the prescriptions Yom Kippur, especially the ceremony by the Kohen Gadol. 8 chapters.
6. Sukkah (סוכה) ("Booth") deals with the festival of Sukkot (the Feast of Tabernacles) and the Sukkah itself. Also deals with the Four Species (Lulav, Etrog, Hadass, Aravah — Palm branch, Citron, Myrtle, Willow) which are waved on Sukkot. 5 chapters.
7. Beitza (ביצה) ("Egg")—now named after its first word, but originally called Yom Tov ("Holidays")—deals chiefly with the rules to be observed on Yom Tov. 5 chapters.
8. Rosh Hashanah (ראש השנה) ("New Year") deals chiefly with the regulation of the calendar by the new moon, and with the services of the festival of Rosh Hashanah. 4 chapters.
9. Ta'anit (תענית) ("Fasting") deals chiefly with the special fast-days in times of drought or other untoward occurrences. 4 chapters
10. Megillah (מגילה) ("Scroll") contains chiefly regulations and prescriptions regarding the reading of the scroll of Esther at Purim, and the reading of other passages from the Torah and Neviim in the synagogue. 4 chapters.
11. Mo'ed Katan (מועד קטן) ("Little Festival") deals with Chol HaMoed, the intermediate festival days of Pesach and Sukkot. 3 chapters.
12. Hagigah (חגיגה) ("Festival Offering") deals with the Three Pilgrimage Festivals (Passover, Shavuot, Sukkot) and the pilgrimage offering that men were supposed to bring in Jerusalem. 3 chapters.

The Jerusalem Talmud has a Gemara on each of the tractates, while in the Babylonian, only that on Shekalim is missing. However, in most printed editions of the Babylonian Talmud (as well as the Daf Yomi cycle), the Jerusalem Gemara to Shekalim is included.

The Jerusalem Talmud (Hebrew: תַּלְמוּד יְרוּשַׁלְמִי, romanized: Talmud Yerushalmi, often Yerushalmi for short) or Palestinian Talmud, also known as the Talmud of the Land of Israel, is a collection of rabbinic notes on the second-century Jewish oral tradition known as the Mishnah. Naming this version of the Talmud after Palestine or the Land of Israel—rather than Jerusalem—is considered more accurate, as the text originated mainly from Galilee in Byzantine Palaestina Secunda rather than from Jerusalem, where no Jews were allowed to live at the time.

The Jerusalem Talmud predates its counterpart, the Babylonian Talmud (known in Hebrew as the Talmud Bavli), by about a century. It was written primarily in Galilean Aramaic. It was compiled between the late fourth century to the first half of the fifth century. Both versions of the Talmud have two parts, the Mishnah (of which there is only one version), which was finalized by Judah ha-Nasi around the year 200 CE, and either the Babylonian or the Jerusalem Gemara. The Gemara is what differentiates the Jerusalem Talmud from its Babylonian counterpart. The Jerusalem Gemara contains the written discussions of generations of rabbis of the Talmudic academies in Syria Palaestina at Tiberias and Caesarea.
