The Talmud is the central text in the Jewish religion. These texts are a record of rabbinic discussions that pertained to Jewish law, ethics, philosophy, customs, and history.
There are two components to the Talmud, as follows: the Mishnah, the first written compendium of the Oral Law of Judaism; and the Gemara, a discussion of the Mishnah and related Tannaitic writings that often covers other components and expounds broadly on the Tanakh.
The six orders of subject matter that can be found in the Talmud are further divided into 60 or 63 tractates of more focused subject matter. Each of these tractates are divided into chapters, 517 in total, and these are numbers according to the Hebrew alphabet and given names.
There are two different Talmud compilations. The language of the Jerusalem Talmud is a western Aramaic dialect, which differs from the form of Aramaic found in the Babylonian Talmud. The law that is laid out in these two compilations is very similar, with the exception of their emphasis and in minor details. Neither the Jerusalem nor the Babylonian Talmud covers the entire Mishnah. This is one of the most important compilations in the Jewish faith.
