Deuteronomy 5:12-15

Observe the sabbath day, to keep it holy, as Jehovah thy God commanded thee. Six days shalt thou labor, and do all thy work; but the seventh day is a sabbath unto Jehovah thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, nor thy man-servant, nor thy maid-servant, nor thine ox, nor thine ass, nor any of thy cattle, nor thy stranger that is within thy gates; that thy man-servant and thy maid-servant may rest as well as thou. And thou shalt remember that thou wast a servant in the land of Egypt, and Jehovah thy God brought thee out thence by a mighty hand and by an outstretched arm: therefore Jehovah thy God commanded thee to keep the sabbath day.
