Rabbinic Judaism or Rabbinism (Hebrew: יהדות רבנית Yahadut Rabanit) has been the mainstream form of Judaism since the 6th century CE, after the codification of the Babylonian Talmud. Growing out of Pharisaic Judaism, Rabbinic Judaism is based on the belief that at Mount Sinai, Moses received from God the Written Torah (Pentateuch) in addition to an oral explanation, known as the "Oral Torah," that Moses transmitted to the people.
