Okay, so if Genesis was re-written in Jeremiah's day, ie. 626-587 BC, we wouldn't expect it to say what it says in 47:26... right?
Hi Spud, You might find the following comments on the authorship of the Pentateuch interesting. Taken from the ESV Study Bible resources. They boast a pretty impressive list of well qualified scholars as being contributors to the ESV translation. In particular note the comment in the final paragraph that, 'it should be seen as originating in Moses’ time but undergoing some
slight revision in later eras so later readers could understand its message and apply it to their own situations.'
For more than 2,000 years, readers of the Pentateuch assumed that Moses was its author (cf. Mark 7:10). This was a natural conclusion to draw from its contents, for most of the laws are said to have been given to Moses by God (e.g., Lev. 1:1), and indeed some passages are explicitly said to have been written down by Moses (see Deut. 31:9, 24). The account of his death could have been recorded by someone else, though some held it was a prophetic account by Moses himself (Deuteronomy 34).
But in the late eighteenth century, critical scholars began challenging the assumption of Mosaic authorship. They argued that several authors were responsible for writing the Pentateuch. These authors supposedly wrote many centuries after Moses, and were separated from each other in time and location. Complicated theories were developed to explain how the Pentateuch grew as different authors’ accounts were spliced and adjusted by a series of editors. According to these critical scholars, it was likely that the Pentateuch reached its final form in the fifth century b.c., nearly a millennium after Moses.
In the late twentieth century this type of critical theory was strongly attacked, not just by conservative scholars but also by those brought up on such theories. They argue that the theories are too complicated, self-contradictory, and ultimately unprovable. It is much more rewarding and less speculative to focus interpretative effort on the final form of the text. So there is a strong move to abandon the compositional theories of the nineteenth and early twentieth centuries for simpler hypotheses. Thus some critical scholars would see the Pentateuch being an essentially fifth-century b.c. creation. Others suggest earlier dates. But none of these suggestions can really be proven.
The Pentateuch does undoubtedly claim to be divine in origin, mediated through Moses. Thus Moses should be looked to as the original human author. Indeed, as stated above, the Pentateuch looks like a life of Moses, with an introduction. But this need not mean that he wrote every word of the present Pentateuch. It seems likely that the spelling and the grammar of the Pentateuch were revised to keep it intelligible for later readers. Also, a number of features in the text look like clarifications for a later age. But this is quite different from supposing that the Pentateuch was essentially composed in a later age. Rather, it should be seen as originating in Moses’ time but undergoing some slight revision in later eras so later readers could understand its message and apply it to their own situations.
