I believe The Lord has made clear His word from the start. When we try to attribute human reason with diety we will always fall short, as well as applying our current cultural systems with that of historical systems and cultures. I don't know how old or where you all are from, but in my 40 years on the Earth in the USA, I have watched American History books be rewritten. My daughter has learned that there are fewer planets than I did, the accounts of American slavery have been altered, presidential monuments are being removed, what was a symbol of promise by God upon the Earth has now been reassigned to represent that which He deems an abomination. So in my 40 years, I've witnessed, in my own country a rearranging of the past 400 years of "his-tory". That does not include the difference of history of these 400 yrs in America taken from the vantage of European, Indian, Chinese, etc cultures. The typical person does not truly care about the cultural history beyond their own bubble. I digress.
My opinion and belief are to use what He defined as His word that would never fade. All of the aforementioned statements, I'd add: the Pharisees told Jesus directly, "Abraham (not Abram, his name before God changed his name) is our father" well, I believe you know where I'm going with this, but I'll continue. Did they live how many years after the death of Abraham? They did not even default to Jacob, the one closest to them. Abraham was great^100th grandfather of them. I am confident the only reason for the mentions of Horeb, Jethro, Reuel is the relation of the bloodline for the sake of proving fulfillment of the prophecies. The name is not of significance beyond the blood attached to it.
As a living example, I have 1 biological child, but I have several that call me momma (I'm actually their athletic coach), though their mothers are in their lives and active. When strangers or associates hear these kids say momma, even the one's whose pigmentation is undeniably different from mine, I can see the questions that loom in their minds, that they are too afraid to ask directly, and as a result, they begin talking among themselves and writing their own conclusions and stories. I've one kid that is genuinely too old to possibly be my biological child, and yet "I gave birth to him while I was in college" I must've been an amazing child prodigy at Stanford at the age of 11! Why not correct them? Truth needs no defense! It rises and withstands time on its own.
I'm no scholar, but personally, as I study, I ask the Holy Spirit to open my eyes to that which I can not see and make clear any questions that may be in me, and though it is not always made clear to me in a single sitting, He always opens my eyes to what is True by definition of His word whether it be in the same day or a year later. I found this site because of the same question that began this feed, and He answered me before I opened this thread, but I wanted to see what others found the solution to be. This is the 3rd site a read through and thought it interesting how much attention is given to the scribes, languages, and textual portion. I've found many answers in the Old testament to be in the new testament. As Jesus is represented as our gateway to God, I see that extends beyond salvation. The New Testament teaches if you seek with a pure heart He will reveal the truth to you. Why did Jesus speak in parables? There are more who seek problems to attempt to discredit His word than those seeking true understanding for the sake of their own daily growth.
