I am not sure how this helps the new testament case though.... it could be seen as evidence that the NT writers were simply building on themes derived from the greek translation and of course the charge is they were fusing Greek religious ideas as well (EG Dionysus). You don't see "Anointed one" translated as Christ from the Masoretic text, or Joshua as Jesus. Joshua was a military leader and "Anointed one" was a label applied to multiple people, including King David, as well as the supposed messiah.
