Deuteronomy 5:13-15

13You have six days each week for your ordinary work,

14but the seventh day is a Sabbath day of rest dedicated to the Lord your God. On that day no one in your household may do any work. This includes you, your sons and daughters, your male and female servants, your oxen and donkeys and other livestock, and any foreigners living among you. All your male and female servants must rest as you do.

15Remember that you were once slaves in Egypt, but the Lord your God brought you out with his strong hand and powerful arm. That is why the Lord your God has commanded you to rest on the Sabbath day.
