Written and oral law
Rabbinic Judaism is distinguished by belief in Moses as "our Rabbi" and that God revealed the Torah in two parts, as both the Written and the Oral Torah, also known as the Mishnah. All the laws in the Written Torah are recorded only as part of a narrative describing God imparting these laws to Moses and commanding him to transmit them to the Jewish nation.
The Talmud contains discussions and opinions regarding details of many oral laws believed to have originally been transmitted to Moses. Some see Exodus 18 and Numbers 11 as a display of Moses' appointing elders as judges to govern with him and judge disputes, imparting to them details and guidance of how to interpret the laws of God while carrying out their duties. The Oral Torah includes rules intended to prevent violations of the laws of the Torah and Talmud, sometimes referred to as "a fence around the Torah". For example, the written Torah prohibits certain types of traveling on the Sabbath; consequently, the Oral Torah prohibits walking great distances on the Sabbath to ensure that one does not accidentally engage in a type of traveling prohibited by the written Torah. Similarly, the written Torah prohibits plowing on the Sabbath; the Oral Torah prohibits carrying a stick on the Sabbath to ensure that one does not drag the stick and accidentally engage in prohibited plowing.
