Deuteronomy 5:13-14

Six days shalt thou labour, and do all thy work; but the seventh day is the sabbath of Jehovah thy God 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.
