Deuteronomy 5:12-15

Be careful to remember the Sabbath day, to keep it holy as the LORD your God has commanded you. You are to labor six days and do all your work, but the seventh day is a Sabbath to the LORD your God. You must not do any work — you, your son or daughter, your male or female slave, your ox or donkey, any of your livestock, or the foreigner who lives within your gates, so that your male and female slaves may rest as you do. Remember that you were a slave in the land of Egypt, and the LORD your God brought you out of there with a strong hand and an outstretched arm. That is why the LORD your God has commanded you to keep the Sabbath day.
