Deuteronomy 5:14-15

14but 1the seventh day is a Sabbath of the Lord your God; you shall not do any work that day, you or your son or your daughter, or your male slave or your female slave, or your ox, your donkey, or any of your cattle, or your 2resident who 3stays with you, so that your male slave and your female slave may rest as well as you. 154And you shall remember that you were a slave in the land of Egypt, and the Lord your God brought you out of there by a mighty hand and an outstretched arm; therefore the Lord your God commanded you to 5celebrate the Sabbath day.
