Deuteronomy 5:13-15

13Six days shalt thou labour, and do all thy work;

14but the seventh day is the sabbath of Jehovah thy 1God: thou shalt not do any work, thou, nor thy son, nor thy daughter, nor thy bondman, nor thy handmaid, nor thine ox, nor thine ass, nor any of thy cattle, nor thy sojourner that is within thy gates; that thy bondman and thy handmaid may rest as well as thou.

15And thou shalt remember that thou wast a bondman in the land of Egypt, and that Jehovah thy 2God brought thee out thence with a powerful hand and with a stretched-out arm; therefore Jehovah thy 3God hath commanded thee to observe the sabbath day.
