“And translated it to Koine”

Oh, please. The jews preserved every single book of their Scriptures in Hebrew. If they didn’t preserve a book in Hebrew, it obviously wasn’t Scripture.

“Different groups in ancient Jewish society held to different canons, but a very large number, if not a majority (even then the diaspora was huge) held to the the Septuagent.”

Oh, which version of the Septuagint would that be? After all, there were multiple versions, with different combinations of apocryphal books included. The only books that are consistent across the different versions are the Hebrew canon that all jews accept.

LOL, keep pulling those covers! Nothing like an educated opposition to the catholicity of Rome.

Do you reject the New Testament? Not written in Hebrew, [parts] not written in Israel, etc.

“The Jews” had no universal or definite canon at the time of Christ — and whatever the codified after His ascension is of no moment. Some Jews (Pharisees, Sadducees, can't remember which) only held 5 books to be divinely inspired. What we do know is that millions of Jews held the 7 books to be Scriptural, but more to the point that both Jesus and the Apostles quoted and treated them as such -- which answers your question as to which version of the Septuagent Jesus used.
