Deuteronomy 5:13-15

13Six days you shall labor and do all your work, 14but 1the seventh day is a sabbath of the Lord your God; in it you shall not do any work, you or your son or your daughter or your male servant or your female servant or your ox or your donkey or any of your cattle or your sojourner who 2stays with you, so that your male servant and your female servant may rest as well as you. 153You 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 by an outstretched arm; therefore the Lord your God commanded you to observe the sabbath day.
