Perhaps I am missing the point as well .....If the written language had no symbols for numbers, they seem to have coped perfecly well, in building cities and temples, keeping a calendar and trading.
Not so fast!
Calendars were based on direct observation of physical certainty. How many moons meant how many moonths (months). This period would be practical to a certain extent. How many suns was more difficult inasmuch as the soon does not travel through "phases".
The number of days in a year was always a problem. The Egyptians tended to use the flooding of the Nile for example.
The common use of so many "fingers" "palms" "feet" etc. is found among many nations.
Using a rope to form a circle of a certain size inadvertently led to the discovery of the ratio between the length of that rope and the circumference of the circle. In other words, the practical proportions of things were carried out and the inherent math automatically followed.
Precision is a fairly modern commodity although precision in ancient times was regarded as a carefully guarded "secret" information to be guarded by priests and master craftsmen guilds.
I said all the above so that I could say this.
IF (conditional premise coming up!) Divine Inspiration were at work in writing the Bible this would SUPERCEDE any necessary knowledge for humans merely transcribing God's thoughts. God would merely REVEAL the unknown thing, the divine mystery, the beautiful equation.
Pi would Pi because God declared it so and not because a human figured it out first.
The haphazard representations of NUMBERS MEASUREMENTS MATHEMATICAL TRUTHS is the bull's eye in my crosshairs here.
You cannot have an accurate Bible Chronology for the very reason there is no SINGLE heuristic at work. Each generation of writers used whatever they thought they knew good or bad. The AUTHOR of the bible is a misnomer. There is no Author (singular) it is a vast superimposition of minds and revisionists and redactors at work.
The icing on that stale cake is the fact they used their alphabet for symbols!
Imagine being a Spanish speaking person thinking in English. Those two languages are different in construction, grammar and rules. You cannot think in BOTH languages at the same time. You go from one "mindset" to the other.
Without an understanding of both languages it is the language you know best which clear when you speak. The language you have acquired secondarily will suffer errors and awkward constructions.
Extrapolate that to using the same set of symbols for language in Hebrew, Greek and Latin and for mathematics (not clearly comprehended.)
A practical test of this is the use of Jesus' own words about the GENERATION not passing away.
The Watchtower has made hay in the sunshine again and again and again BECAUSE THERE IS NO MATHEMATICAL CERTAINTY contained in the word at all!
This is true of all Bible statements and alphmeric-numbers!
