In Abrahamic religions, the Sabbath or Shabbat 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. The practice of observing the Sabbath (Shabbat) originates in the biblical commandment "Remember the sabbath day, to keep it holy".
For the Abrahamic religions: Judaism, Seventh Adventist Christians, and Samaritanism Sabbath begins Friday at sundown and ends at Saturday sundown. Thus the sunset is a common symbology of the Sabbath.
