Exodus 20:8-11
20:8 “Remember the Sabbath day to set it apart as holy.
20:9 For six days you may labor and do all your work,
20:10 but the seventh day is a Sabbath to the Lord your God; on it you shall not do any work, you, or your son, or your daughter, or your male servant, or your female servant, or your cattle, or the resident foreigner who is in your gates.
20:11 For in six days the Lord made the heavens and the earth and the sea and all that is in them, and he rested on the seventh day; therefore the Lord blessed the Sabbath day and set it apart as holy.
