You asked : "My question is simple – how do we KNOW which text is right and which spellings were
given by God so we could discover his code?"
Hi Kenneth, I am not a scholar but I would like to answer this question from a podium called "Logical reasoning" if I may.
1. Older has never meant more reliable. It annoys me in some Textual writings especially in some bible introductions that "they accessed the most reiiable and oldest known Ms" this is an oxymoronic statement.
2. So God says: "Oops, terribly sorry chaps, it's been 2500 years and finally I am able to give you my word and so it is a Pity the last 100 generations who never seem to have accomplished much from what apparanlty had so many errors but I waited till 1947 for you to discover the Truth".
3. In year 1 I write abc, in year 2 someone copies mine and writes abd, in year 3 someone else copies mine and writes abc. MS from year 1 is lost. Which is more reliable? The oldest or the youngest MS?
So I think we can safely say on many fronts (including theological ones I have not mentioned because this is not appropriate) that what has been handed down to us by the masoretes, kept preserved by God's hand, is the faithful text.
