Exodus 20:10
but the seventh day is a Sabbath to the LORD your God, on which you must not do any work—neither you, nor your son or daughter, nor your manservant or maidservant or livestock, nor the foreigner within your gates.
Leviticus 23:3
For six days work may be done, but the seventh day is a Sabbath of complete rest, a day of sacred assembly. You must not do any work; wherever you live, it is a Sabbath to the LORD.
