Oral Torah

According to Rabbinic Judaism, the Oral Torah or Oral Law (Hebrew: תורה שבעל פה, Torah she-be-`al peh, lit "Torah that is spoken") represents those laws, statutes, and legal interpretations that were not recorded in the Five Books of Moses, the "Written Torah" (Hebrew: תורה שבכתב, Torah she-bi-khtav, lit. "Torah that is written"), but nonetheless are regarded by Orthodox Jews as prescriptive and co-given. This holistic Jewish code of conduct encompass a wide swath of ritual, worship, God-man and interpersonal relationships, from dietary laws to Sabbath and festival observance to marital relations, agricultural practices, and civil claims and damages.

According to Jewish tradition, the Oral Torah was passed down orally in an unbroken chain from generation to generation until its contents were finally committed to writing following the destruction of the Second Temple in 70 CE, when Jewish civilization was faced with an existential threat.

The major repositories of the Oral Torah are the Mishnah, compiled between 200–220 CE by Rabbi Yehudah haNasi, and the Gemara, a series of running commentaries and debates concerning the Mishnah, which together are the Talmud, the preeminent text of Rabbinic Judaism. In fact, two "versions" of the Talmud exist: one produced in Jerusalem c. 300–350 CE (the Jerusalem Talmud), and second, more extensive Talmud compiled in Babylonia and published c. 450–500 CE (the Babylonian Talmud).
