That is not in Romans. In fact, those chapters things that are directly opposite of what you state:
Romans 9:
4 They are Israelites, and to them belong the adoption, the glory, the covenants, the giving of the law, the worship, and the promises.
5 To them belong the patriarchs, and from their race, according to the flesh, is the Christ who is God over all, blessed forever. Amen.
6 But it is not as though the word of God has failed. For not all who are descended from Israel belong to Israel,
7 and not all are children of Abraham because they are his offspring, but “Through Isaac shall your offspring be named.”
8 This means that it is not the children of the flesh who are the children of God, but the children of the promise are counted as offspring.
There are other verses, but true to my word (and your claim was so outrageously contrary to Scripture, I felt compelled to respond) so let's return to the OP..
