"Most scholars" set the dates for the writing of the Pentateuch (aka Torah) at about 1250 BC? (By Moses himself, perhaps?) I'd be surprised.
When I first looked into this, the most common hypotheses were variations of the so called Documentary Hypothesis, which held that while some of the sources of the Torah may have existed in writing back to 950 BC, the actual composition took place about 500 BC. I had the distinct impression most scholars held to some of these hypotheses.
Later, I've been told that the sources I thought went back to 950 BC, were probably from the time of the Babylonian exile. I have not looked into it, but from what I was told, this was being accepted by most modern scholars. Also, I've been told that other hypotheses have been gaining traction, in which the Torah was not composed from several longer documents, but either from many fragments or incrementally. I get the impression they still place the completion of the work around 500 BC, though.
If I go to vatican.va, click "English", "Resource Library", "The Bible" (twice), and "The Pentateuch", I get to
http://www.vatican.va/archive/ENG0839/__P2.HTM ... which restates the essentials of the Documentary Hypothesis, and tells us: "all was brought together in writing, about the sixth century B.C., when the literary formation of the Pentateuch came to an end".
Sure, that's just the Vatican. It does not preclude "most scholars" setting the writing of the Torah at about 1250 BC. But I'd be surprised.
