Deuteronomy 5
13 Ref On six days do all your work:
14 Ref But the seventh day is a Sabbath to the Lord your God; on that day do no work, you or your son or your daughter, or your man-servant or your woman-servant, or your ox or your ass or any of your cattle, or the man from a strange country who is living among you; so that your man-servant and your woman-servant may have rest as well as you.
15 Ref And keep in mind that you were a servant in the land of Egypt, and that the Lord your God took you out of that land by his strong hand and his stretched-out arm: for this reason the Lord has given you orders to keep the Sabbath day.
