Gordon's speculation isn't compelling, not least because Abraham was a Semite, and "Hittite" is not a Semitic language, which leaves him right out of the "Hittite" royal family.
Add to that, the big "Hittite" archive had loads of cuneiform tablets, most of which were in two languages (neither one is Semitic), with a smattering of other languages (including some Assyrian, which is a Semitic language) here and there. The names for the languages given *in* the languages are not "Hittite" or "Hattish" (the two working names picked in modern times), and the name "Hittites" was picked from the OT.
“Gordon’s speculation isn’t compelling”
That was not Gordon’s speculation, it was my tongue-in-cheek comment that got your panties in a wad.
However, I would value Gordon’s speculation light years ahead of anything you say.
I once suggested that calling a group of people “Hittites” when they speak another language entirely, is like calling the people in Albany, New York “Albanians.”
