I thought the Jews didn’t have anything like an actual canon (except for the Sadduccees accepting only the Torah) untl Yavneh (the form I prefer to Jamnia).
“Rabbinic Judaism recognizes the twenty-four books of the Masoretic Text, commonly called the Tanakh or “Hebrew Bible”. Evidence suggests that the process of canonization occurred between 200 BC and AD 200, indeed a popular position is that the Torah was canonized circa 400 BC, the Prophets circa 200 BC, and the Writings circa AD 100[5] perhaps at a hypothetical Council of Jamnia—however this position is increasingly criticised by modern scholars.”
That is Wiki, but I could dig out other sources for the same thing if I wanted to spend the time.
There was a canon from the time of Nehemiah, this canon is discussed in maccabees 2
Jesus himself divided the canon before Jamnia
Luke 24:44 And he said unto them, These are the words which I spake unto you, while I was yet with you, that all things must be fulfilled, which were written in the law of Moses, and in the prophets, and in the psalms, concerning me.
Luke 24:45 Then opened he their understanding, that they might understand the scriptures,
