Deuteronomy 5:12-15

12“‘Observe the Sabbath day, to keep it holy, as the  Lord your God commanded you. 13Six days you shall labor and do all your work, 14but a  the seventh day is a Sabbath to the  Lord your God. On 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 livestock, or the sojourner who is within your gates, b  that your male servant and your female servant may rest as well as you. 15 c  You shall remember that you were a slave
Or servant
in the land of Egypt, and the  Lord your God brought you out from there e  with a mighty hand and an outstretched arm. Therefore the  Lord your God commanded you to keep the Sabbath day.
