3 For I could wish that I myself were accursed and separated from Christ for the sake of my brothers, my kin according to the flesh.
4 They are Israelites; theirs the adoption, the glory, the covenants, the giving of the law, the worship, and the promises;
5 theirs the patriarchs, and from them, according to the flesh, is the Messiah. God who is over all be blessed forever. Amen.
6 But it is not that the word of God has failed. For not all who are of Israel are Israel,
7 nor are they all children of Abraham because they are his descendants; but “It is through Isaac that descendants shall bear your name.”
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 descendants.
9 For this is the wording of the promise, “About this time I shall return and Sarah will have a son.”
