The Mishnah is the portion of the Talmud that contains the written version of the Oral Law given to Moses along with the Torah, which comprises the written law of Judaism. Traditionally, it was held that the oral law should not be written down and must be transmitted by word of mouth.

The Mishnah is written in Hebrew and deals almost entirely with the legal aspects of Jewish tradition, the halacha. It was standardized by Rabbi Judah ben Simeon, also known as Judah ha Nasi, the Hebrew word for Prince. It is believed to have been written around the year 217 CE.
