Don't have to, my copy is in English. The point of the thread is it's more accurate than the Masoretic Text and was written earlier than the MT. Jesus quoted the LXX, not the MT. The MT is much later than the LXX. There are mistakes in the MT and that moved into the KJV.
Let's just say that it APPEARS to have been written earlier; according to the evidence we now have in hand.
I wonder what would happen to the 'accuracy' claim if a MT is discovered that chrono testing shows that it predates The Septuagint?
