Sabbath

The Sabbath is a religious day set as a day of rest by God for His people, as mentioned in the Holy Bible. In Judaism, Saturday, or "the seventh day", is set as a day of rest as well as other days in the religious calendar (referred to as a High Sabbath), while in mainstream Christianity, Sunday is set as a day of rest.
