Tanach Thoughts

According to Shmuel 1:10:21 , Shaul's family was part of a clan called Matri (Matrites). Curiously, in aggadic descriptions of Shaul's full genealogy all the way to Binyamin, Matar or Matri or Matari or something similar is nowhere to be found (see here ). Little is otherwise known about this clan. Ze'ev Erlich thought  that the Matrites lived in what is now known as Khirbet Rimnah, as nearby there's a later site called Khirbet al-Matari - evidently preserving the name of the Matrites. Both sites are located in the vicinity of the Gibdeonite cities, and since it's known that Shaul's family came from that region, this suggestion is quite plausible. The name of the forefather of the family, Matar or Matari or Matri, shares the root of MTR (מט"ר), 'rain' (often referring to abundant rain). However, a few days ago I came across another possibility: This article by Norbert Nebes (p. 19, line 3) mentions that in Ethio-Sabaean, a 1st millennium BCE Semiti...

A thought that I had a bit earlier: When I think about the word "dvir" (דביר), I understand what it's used to refer to: The inner sanctum of a temple (also borrowed to refer to a city in Eretz Yehudah). But I don't know the etymology of the word. What does the word itself literally mean? What do all of its parts put together mean? Why does dvir specifically mean inner sanctum? Well, I don't have a clear answer on that, but I had a thought: Many letters in Semitic languages are interchangeable and often get switched around. And it just so happens that all of the letters in dvir can be interchanged. In this case, some meaning of the word dvir can be leaned by switching three of its four letters: ד, י, ר with their parallels ז, ו, ל. Keeping the ב, we get the word "Zvul" (זבול) which is also a term used to refer to a temple, or part of a temple. I think that's pretty neat.
