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

Isaiah cries out concerning Israel, “Though the number of the sons of Israel be like the sand of the sea, it is the remnant that will be saved;

but Israel, pursuing a law of righteousness, did not arrive at that law.

But I say, surely Israel did not know, did they? First Moses says,
“I will make you jealous by that which is not a nation,
By a nation without understanding will I anger you.”

But as for Israel He says, “All the day long I have stretched out My hands to a disobedient and obstinate people.”

God has not rejected His people whom He foreknew. Or do you not know what the Scripture says in the passage about Elijah, how he pleads with God against Israel?

What then? What Israel is seeking, it has not obtained, but those who were chosen obtained it, and the rest were hardened;

For I do not want you, brethren, to be uninformed of this mystery—so that you will not be wise in your own estimation—that a partial hardening has happened to Israel until the fullness of the Gentiles has come in;

and so all Israel will be saved; just as it is written,
“The Deliverer will come from Zion,
He will remove ungodliness from Jacob.”
