Shabbat (Hebrew: שבת‎) is first tractate (book) in the Order (Mishnaic section) of Moed, of the Mishnah and Talmud. The tractate consists of 24 chapters. The tractate primarily deals with laws relating to Shabbat (the weekly day of rest), and the activities prohibited on Shabbat (the 39 prohibitions) and distinguishes between Biblical prohibitions and Rabbinic prohibitions. It also discusses special Rabbinic decrees to reinforce the concept of rest on Sabbath (see muktzah, articles that may not be used or moved on Sabbath, chapters 3 and 17) and to enhance its sanctity, such as forbidding pursuit of business and discussing forbidden matters (chapter 23) and pursuing weekday activities.
