Two Views

So how does one reconcile the fact of textual updating to the belief of inspiration and inerrancy?

There are two views on this:

1. Non-inspired Textual Updating (traditional view): Authored by Moses, the original copy (autographa)
of the Pentateuch was inspired and any later additions, while still true and correct, were not inspired.
These geographical, historical, or linguistic updates are considered as secondary textual variants of the original inspired autographa.

2. Inspired Textual Updating: Authored by Moses, the original copy (autographa) of the Pentateuch
was inspired, but was in its preliminary canonical form. Later geographical, historical, or linguistic updates were inspired and were just as true and correct as the original inspired text until the inscripturation
process and canon were completed.
