Exactly right, they had the unedited canon. The exact same canon used in the LXX.
“Exactly right, they had the unedited canon. The exact same canon used in the LXX.”
If you choose to interpret history that way, I support your right to do so, but ...
I will tell you I think it stretches credulity to choose to believe that for some reason, a tiny offset of isolated Jews knew more than the Jews in Jerusalem - who rejected the Apocrypha as inspired. Again, you will choose what to believe and I’m not trying to persuade you either way.
Does this line of argument make sense that some Jews somewhere believed the Apocrypha was inspired because you want to believe the same and need some kind of evidence? Or do you really believe it has the ring of historical truth?
It seems more likely to me that when Beta Israel initially went into exile they took with them the Septuagint, or acquired it in another way.
Best.
