Was this the Septuagint version?
Once I saw this guy on a bridge about to jump. I said, Dont do it! He said, Nobody loves me. I said, God loves you. Do you believe in God?
He said, Yes. I said, Are you a Christian or a Jew? He said, A Christian. I said, Me, too! Protestant or Catholic? He said, Protestant. I said, Me, too! What franchise? He said, Baptist. I said, Me, too! Northern Baptist or Southern Baptist? He said, Northern Baptist. I said, Me, too! Northern Conservative Baptist or Northern Liberal Baptist?
He said, Northern Conservative Baptist. I said, Me, too! Northern Conservative Baptist Great Lakes Region, or Northern Conservative Baptist Eastern Region? He said, Northern Conservative Baptist Great Lakes Region. I said, Me, too!
Northern Conservative Baptist Great Lakes Region Council of 1879, or Northern Conservative Baptist Great Lakes Region Council of 1912? He said, Northern Conservative Baptist Great Lakes Region Council of 1912.
I said, Die, heretic! And I pushed him over.
Your question is a good one, but the answer is not simple. While the fragments are pretty well all Hebrew or Aramaic, there are readings that support the LXX against the MT (Masoretic Text—the Hebrew text adopted as official about a thousand years ago), and there are readings that support the MT against the LXX. Individual passages of individual books have to be spoken about to give a specific answer.
