About biblical authenticity- Greek & Latin?

[Jona Lendering]

Since there were Jewish congregations throughout the Roman Empire; It would make sense that, before the advent of Christ and the evangelization that followed, that these congregations would have commissioned their own translation of the Torah texts. Such translations would have been bebeficial to converts and potential converts to Judaism. Does anyone kow when the earliest translations can be dated to? Also in what languages?

Septuaginta again (Stefanos' Metafrasi ton Eudomokonta) for Greeks; and there were half a dozen "targums" for Aramaic speaking people.
