According to Jewish tradition, the Torah contains 613 commandments. This tradition is first recorded in the 3rd century CE, when Rabbi Simlai mentioned it in a sermon that is recorded in Talmud Makkot 23b. Other classical sages who hold this view include Rabbi Simeon ben Azzai and Rabbi Eleazar ben Yose the Galilean. It is quoted in Midrash Exodus Rabbah 33:7, Numbers Rabbah 13:15–16; 18:21 and Talmud Yevamot 47b. The 613 commandments include "positive commandments", to perform an act, and "negative commandments", to abstain from an act. The negative commandments number 365, which coincides with the number of days in the solar year, and the positive commandments number 248, a number ascribed to the number of bones and main organs in the human body.

Judaism is an Abrahamic, monotheistic, and ethnic religion, comprises the collective spiritual, cultural, and legal traditions of the Jewish people. Contemporary Judaism having originated as an organized religion in the Middle East during the Bronze Age, and evolved from Yahwism, the cultic polytheistic religious movement of ancient Israel and Judah, around the 6th/5th century BCE, and is thus considered to be one of the oldest monotheistic religions. Along with Samaritanism, to which it is closely related, Judaism is one of the two oldest Abrahamic religions.
