Re: Daniel 9:24-27. How & why do you separate the 70th week from the 69th. There is no indication by Daniel that there is supposed to be a separation.
Had Israel accepted Jesus as their Messiah there would have been no separation between the 69th and 70th weeks of Daniel’s prophecy. But because they didn’t there is one.
We know this because the only events described in Daniel 9:26-27 that have taken place are that the Anointed One (Jesus) was cut off (executed) and the people of a prince who will come destroyed the city (Jerusalem) and the sanctuary (Temple). The rest awaits a future fulfillment which requires a temple, and there hasn’t been one since the Romans destroyed the last one in 70AD.
