There was no Jewish canon until well after the Second Temple was destroyed.
The Zadokite priesthood (known to Christians as the Sadduccees) and their adherents insisted that only the five books of the Torah were Scripture.
The Perushim (known to Christians as the Pharisees) insisted that prophetic and historical works were part of the canon as well.
Most Jews worldwide used the Septuagint as their text, since most Jews knew Greek better than Hebrew.
There were disputes among different Jewish schools as to what list of books should accompany the Torah.
There were also various Aramaic translations of the Torah and the Prophets being used in different synagogues - these were known as Targums.
It wasn't until after the destruction of the Second Temple that the school of Yochanan ben Zakkai began advocating a very specific, Pharisaic list of canonical books.
I understand that Christians, especially Catholics, have an alternative to the Jewish history. I’ll just point out that Jewish scholars disagree. Two different religions, after all.
Besides, the real fight is between Protestants and Catholics, who do not agree on canon and claim to be the same religion.
Wrong most Jews then spoke Aramaic as the largest communities were in Israel and Babylonia. Jews in Alexandria spoke Greek as did Jews of Greece. Jews of Rome spoke Latin.
educated Jews everywhere used Hebrew and Aramaic for their liturgy.
never was a pagan language like Greek ever elevated to the sanctity of Hebrew.
