And, unless I am wrong - that the Bible is silent on the development of “Hebrew”, it “evolved” over time and with the living experience of “the Jews” and most likely in the same human context that Aramaic script developed.
Is the settlement of this mystery important? To language scholars and just understanding written language history, yes; to Judeo-Christian faith, no. In my own personal view.
It’s been called the flaming language with reference to spiritual etymology. Perhaps it predates man.
You really made it look as if you were interested, but since this isn’t important to you, why post?
By the time Judaism arose, Hebrew had been supplanted by Aramaic. Abraham spoke — did not write — Hebrew.
