The Talmud (/ˈtɑːlmʊd, -məd, ˈtæl-/; Hebrew: תַּלְמוּד, romanized: Talmūḏ, lit. 'teaching') is the central text of Rabbinic Judaism and the primary source of Jewish religious law (halakha) and Jewish theology.[1][2] Until the advent of modernity, in nearly all Jewish communities, the Talmud was the centerpiece of Jewish cultural life and was foundational to "all Jewish thought and aspirations", serving also as "the guide for the daily life" of Jews.[3]
The term Talmud normally refers to the collection of writings named specifically the Babylonian Talmud (Talmud Bavli), compiled in the 5th century by Rav Ashi and Ravina II. There is also an earlier collection known as the Jerusalem Talmud (Talmud Yerushalmi).[4] It may also traditionally be called Shas (ש״ס), a Hebrew abbreviation of shisha sedarim, or the "six orders" of the Mishnah.
