Exodus 20:8-11 NRSV
Remember the sabbath day, and keep it holy. Six days you shall labor and do all your work. But the seventh day is a sabbath to the LORD your God; you shall not do any work—you, your son or your daughter, your male or female slave, your livestock, or the alien resident in your towns. For in six days the LORD made heaven and earth, the sea, and all that is in them, but rested the seventh day; therefore the LORD blessed the sabbath day and consecrated it.
