im not sure where to post this but i think its telling
not long but read it closely i get a bit confused on the latter half
the question is did God establish his covenant with the gentile nations or the Jews.. [though i have read from a jewish web source, that the jews have nothing to do with Israel and the greek scriptures or half the Hebrew scriptures ]

the way i understand it it that no one other than Israel has a covenant with God and it is still in effect basically
it is the gentiles who choose to join Israel and their covenant who are then taken into consideration. not those who stay apart from that nation. also there is no symbolism apparently, its to be taken literal. other than the obvious literary symbolism.
