First, we should note there is but one sabbath each week. It falls on the seventh day (Exodus 16:26). No one can change that fact. Despite what many say, Sunday is not the sabbath.
Second, the sabbath was bound by God upon the children of Israel at Sinai (Nehemiah 9:13,14). It had not previously been known or kept by their fathers (Deuteronomy 5:2,3). The children of Israel were to keep the sabbath as a continual sign of their covenant with God (Exodus 31:12-17).
