The order to keep the Sabbath day is a work followed by the Jews, who believe that this is an order from God, since God, when creating human beings and the whole universe used 6 days, leaving the seventh day to rest and observe your work.
Thus, because it is a commandment from God that the Jews follow, we can affirm that this commandment has a God-believer relationship, being followed by all those who believe that this is correct.
