The Mishnah is the first written collection of the Jewish oral traditions. These oral traditions are known as the "Oral Torah", to differentiate them from the (written) Torah, and both are believed in rabbinic tradition to have been revealed alongside each other to Moses at Mount Sinai. While the Torah was passed down in writing, the Oral Torah is believed to have been transmitted by Jewish scholars until the compilation of the Mishnah in the late second or early third century CE. The Mishnah is viewed as authoritative and binding revelation by most Orthodox Jews and some non-Orthodox Jews. The Mishnah is also the basis of the Babylonian Talmud and the Jerusalem Talmud, which are both commentaries on the Mishnah.
