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.
Deuteronomy 5:12–14
Observe the Sabbath day by keeping it holy, as the LORD your God has commanded you. / Six days you shall labor and do all your work, / 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, nor your ox or donkey or any of your livestock, nor the foreigner within your gates, so that your manservant and maidservant may rest as you do.
