RR:IMO that can hardly be deduced from Luke 21:24, which refers to future events:
they will fall by the edge of the sword and be taken away as captives among all nations (ethnè = "Gentiles"); and Jerusalem will be trampled on by the Gentiles, until the times of the Gentiles are fulfilled.
Btw, what do you think of 607/6 as a starting point? I guess you've been asked the question thousands of times, but I have not read your answer yet.
