The Meaning of the Fourth Commandment (4) Rest for Everyone

The Fourth Commandment is a transition between the first table of the law which is focused on our duty toward God and the second table of the law which is focused on our duty towards our fellow human beings. It requires that we set a day apart for the worship of God, but it also requires that the people who work for us and the weaker members of society share in the blessings of the Sabbath. The concern is that those who have the money and the power to have other people working for them, do not require those people to work for them on the Sabbath day. So the Sabbath is both about our duty towards God and our duty towards other people.
