The unique history of the People of Israel would have been preached even if the Torah (first 5 books of the Bible) had not foreseen it in advance. The very fact that the Torah did foresee it and described it in a clear and unambiguous prophecy (at the end of Deuteronomy, chapters 28-21), clearly testifies to the truth of the Torah and that it was given by GOD.
Only a supreme power that controls history could have ensured the existence of the People of Israel when they were scattered in exile, under conditions in which all other peoples were soon assimilated or destroyed; make sure they always stayed small and persecuted and did not find rest in the Diaspora; kept their country desolate in anticipation of their return despite the attempts of many to conquer and settle it; and ultimately gather the outcasts of Israel from all corners of the globe, bring them back to their land, and help them establish a prosperous state while overcoming armies stronger than them, absorbing mass immigration, and many other problems.
