In Deuteronomy 5, Moses is reminding the Israelites to follow the Law and, in particular, the Ten Commandments. When Moses speaks the command to observe the Sabbath, the reason he gives for observing it is different than the reason God gave to Moses in Exodus. There, the command was connected to the Creation. In Deuteronomy, it's connected to liberation. Moses says, "Remember that you were slaves in Egypt 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." It's an instruction that extends not just to the people hearing Moses, but to their children, their workers, their animals, and even the immigrants residing among them. The Sabbath is for everyone. And until everyone can experience rest unto the LORD, it's only a privilege for some, rather than a gift for all.
