'Sabbath' in the Bible

""Observe the Sabbath day, maintaining its holiness, just as the LORD your God commanded.

but the seventh day is a Sabbath to the LORD your God. You are not to do any work neither you, your son, nor your daughter, your male and female servants, your oxen and donkeys, nor any of your livestock, nor any foreigner who lives among you, so that your male and female servants may rest as you do.

You are to remember that you were a slave in the land of Egypt, but the LORD your God brought you out from there with great power and a show of force. Therefore, the LORD your God has commanded you to observe the Sabbath day.
