Romans 9:3-7

For I could wish that I myself were accursed, separated from Christ for the sake of my countrymen, my kinsmen according to the flesh,

who are Israelites, to whom belongs the adoption as sons and daughters, the glory, the covenants, the giving of the Law, the temple service, and the promises;

whose are the fathers, and from whom is the Christ according to the flesh, who is over all, God blessed forever. Amen.

But it is not as though the word of God has failed. For they are not all Israel who are descended from Israel;

nor are they all children because they are Abraham’s descendants, but: “through Isaac your descendants shall be named.”
