That's a very vague statement.Israel would not accept the Gentiles.
Are you saying that the gentiles attacked Israel because Israel would not accept them? It's not clear why you posted this scripture with your earlier statement.They will fall by the sword and will be taken as prisoners to all the nations. Jerusalem will be trampled on by the Gentiles until the times of the Gentiles are fulfilled" (Luke 21:24).
Again, why this scripture? This one is completely unrelated to the first one that you posted."I do not want you to be ignorant of this mystery, brothers and sisters, so that you may not be conceited: Israel has experienced a hardening in part until the full number of the Gentiles has come in" (Romans 11:25).
