what is the definition of sabbath in hebrew
Shabbat Shabbat (/ʃəˈbɑːt/; Hebrew: שַׁבָּת‎ [ʃa'bat], "rest" or "cessation") or Shabbos (['ʃa.bəs], Ashkenazi Hebrew and Yiddish: שבת‎), or the Sabbath is Judaism's day of rest and seventh day of the week, on which religious Jews, Samaritans and certain Christians (such as Seventh-day Adventists, the 7th Day movement and Seventh Day Baptists) remember the Biblical creation of the heavens and the earth in six days and the Exodus of the Hebrews, and look forward to a future Messianic Age. Shabbat observance entails refraining from work activities, often with great rigor, and engaging in restful activities to honor the day. Judaism's traditional position is that unbroken seventh-day Shabbat originated among the Jewish people, as their first and most sacred institution, though some suggest other origins. Variations upon Shabbat are widespread in Judaism and, with adaptations, throughout the Abrahamic and many other religions.
Sunday For most observant Christians, Sunday is observed as a day of worship and rest, holding it as the Lord's Day and the day of Christ's resurrection. In some Muslim countries and Israel,[citation needed] Sunday is the first work day of the week. According to the Hebrew calendars and traditional Christian calendars, Sunday is the first day of the week.[1] However, according to the International Organization for Standardization ISO 8601, Sunday is the seventh and last day of the week.[2]
