Observe the Sabbath day by keeping it holy as the Lord your God has commanded you. Six days you shall labor and do all your work, but the sebenth day is a Sabbath to the Lord your God. On it you shall not do any work, neither you, nor your so or daughter, nor your manservant or maidservant, nor your ox or donkey or any of your animals,nor the alien within your gates, so that your manservant and maidservant may rest as you do. Remember that you were slaves in Egypy and that the Lord your God brought you out of there with a mighty hand and an outstretched arm. Therefore the Lord your God has commanded you to observe the Sabbath day.
Deuteronomy 5:12-15
