In Abrahamic religions, the Sabbath (/ˈsæbəθ/) or Shabbat (Biblical 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 Yahweh to be kept as a holy day of rest as God rested in the Genesis creation narrative. 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.
A day of rest is observed in Islam (Friday), Judaism (Saturday), and Christianity (Sunday). 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.
