Torah From Sinai?

The sidra begins with the report that the commandment to keep the Shemita-Sabbatical year, was given at Sinai . The question is , of what significane is it to us that the Commandment came at Sinai? On a scale of 1- 10 what change in our attitude towards the Torah would change if we knew
that it came from Sinai?Probably 1!
The classic commentaries in the Midrash quote Rabbi Yishmoel and Rabbi Akiva who argue if all of the Torah down to every minor detail was given when Moshe went up on Sinai or whether the details were included later .Both agree that the general principles werew delivered at Sinai only the details are in question. Both agree , however that the commandment for the Sabbatical year was given with its' details around the time of the giving of the Torah . The only question was where were the details first discussed . Rabbi Yishmoel opines that they were given in detail at the Ohel Moed- The Tabernacle. Rabbi Akiva says that the details too were given at Mt. Sinai . The difference is inherent in the very nature of the Oral Law . Rabbi Yishmoel is of the opinion that the details of the law were in essence logical out growths of the principles . Rabbi Akiva , however apparently holds that the details were also Prophetic in nature .
This is the reason for the need to identify the Sabbatical Year with Sinai . This teaches that all of the Torah's commandments as well as their details are truly Prophecies . Furthermore , the enactments of subsequent generations receive this exalted status as well . The Laws of the Torah can be questioned and argued about. In the end the reason we obey them is because we believe that they are G-D given!
