and that some of the Greeks took considerable pains to know the affairs of our nation.  I found, therefore, thatthe second of the Ptolemies was a king who was extraordinarily diligent in what concerned learning, and the collection of books; that he was also peculiarly ambitious to procure a translation of our law, and of the constitution of our government therein contained, into the Greek tongue.
[Antiquities of the Jews – Book I,9-10]

[Antiquities of the Jews 12.11]
