Sabbath
In Abrahamic religions, the Sabbath (/ˈsæbəθ/) or Shabbat (from Hebrew שַׁבָּת [ʃa'bat]) is a day set aside for rest and worship. According to the Book of Exodus, the Sabbath is a day of rest on the seventh day, commanded by God to be kept as a holy day of rest, as God rested from creation. Sabbath (Shabbat) observance is commanded in the Ten Commandments: "Remember the sabbath day, to keep it holy". The Sabbath might have been influenced by Babylonian mid-month rest days and lunar cycles, though its origins remain debated.
The Sabbath is observed in Judaism, Islam, and by some Christian groups. Observances similar to, or descended from, the Sabbath also exist in other religions. The term may be generally used to describe similar weekly observances in other religions.
