Says who?

Not the jews, that’s for sure. They wrote their Scripture in Hebrew.

And translated it to Koine. Are you suggesting that your own copy of the Bible is invalid because it is in English instead of Hebrew?

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. Jesus quoted from the Septuagent, and from the deuterocanonical books contained within it.
