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.
Lord's Day According to some sources, Christians held corporate worship on Sunday in the 1st century.[1] The earliest Biblical example of Christians meeting together on a Sunday for the purpose of "breaking bread" and preaching is cited in the New Testament book The Acts of the Apostles chapter 20 and verse 7 (Acts 20:7). 2nd-century writers such as Justin Martyr attest to the widespread practice of Sunday worship (First Apology, chapter 67), and by 361 AD it had become a mandated weekly occurrence. During the Middle Ages, Sunday worship became associated with Sabbatarian (rest) practices. Some Protestants today (particularly those theologically descended from the Puritans) regard Sunday as Christian Sabbath, a practice known as first-day Sabbatarianism. (Some Christian groups hold that the term "Lord's Day" can only properly refer to seventh-day Sabbath or Saturday.)
