From what I have read about the way Jews follow the Sabbath, it is expressly forbidden to sew, skin an animal or cut patterns, yet God apparently did just that for Adam and Eve.
The scripture in Genesis states God made the garments, not anyone else.
I have also heard a lot said from JW land and other Christian commentators, about how God must have changed something in the chemistry of animals because before sin entered the world they were all vegetarians.
Once you factor in all the miracles attributed to God, as well as all the other stuff, it seems like a lot of work for a day of inactivity.
I wonder how many followers of the old testament have been, or still are being persecuted for not following the Sabbath to the letter?
