In the Hebrew Bible, or Tanakh, the root Sh-B-T is used to describe God resting on the seventh day. This is the day after He finished creating the universe. In the Bible, the idea of Shabbat, or Sabbath, as a holy day of rest starts there.
Remembering and keeping Sabbath is also one of the Ten Commandments. From that, the Abrahamic religions (Judaism, Christianity and Islam) all have a tradition of a holy day of rest or prayer set aside every week. These days are now very different from each other, including which day of the week they fall on.
- Genesis 2:1-3
- Some scholars believe that the writers of the Bible got the idea of the Sabbath from the Babylonians. See, for example, Craveri, Marcello (1967). The Life of Jesus. Grove Press. p. 134. ASIN B00DLK4P48.
- Exodus 20:7-10 and Deuteronomy 5:11-14. Some translations have different verse numbers.
