Onthewayout you got interesting thoughts.
Why do you so confident that no people EVER lived under the Mosaic Law Code?
Archeaology has amply demonstrated that the events of Genesis and Exodus simply did not happen. There may have been an Abraham, but everything before that is just stories that may or may not be even loosely based on any reality. SO that would include the establishing of the law.
While all the books of the Torah may have had some beginnings earlier, it appears that they were brought about perhaps in the time of King Josiah and tinkered with until the return from exile in Babylon.
That means that they referred back to a people that lived under the law. But the establishment of that law (the time of and after Moses) was a fiction, so writing about people under the law was fiction. The Jews never really tried to live up to any law code after the exile.
I do not refer to a people that tried and failed to live up to the law. The law as a whole did not exist until it was compiled and written after the time it pretends to acurately reflect. Some of the people lived under some of the rules that became "the law" but nobody had all of the law enforced upon them.
Note this from: http://en.wikipedia.org/wiki/Law_of_Moses
The Book of Kings relates how a "law of Moses" was discovered in the Temple during the reign of king Josiah (r. 641–609 BCE). This book is mostly identified as an early version of the Book of Deuteronomy, perhaps chapters 5-26 and chapter 28 of the extant text. This text contains a number of laws, dated to the 8th century BC kingdom of Judah, a time when a minority Yahwist faction was actively attacking mainstream polytheism, succeeding in establishing official monolatry of the God of Israel under Josiah by the late 7th century BC.
I won't stand by my statement as if that is the end of the matter. It's too difficult to prove, but I am confident from my readings that nobody ever lived under the law. Various people have lived under chosen parts of it, but nobody ever even came close to living under all of it.
