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

But Isaiah cries out concerning Israel:

Though the number of Israel’s sons
is like the sand of the sea,
only the remnant will be saved;

But Israel, pursuing the law for righteousness, has not achieved the righteousness of the law.

But I ask, “Did Israel not understand?” First, Moses said:

I will make you jealous
of those who are not a nation;
I will make you angry by a nation
that lacks understanding.

But to Israel he says: All day long I have spread out My hands to a disobedient and defiant people.

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

What then? Israel did not find what it was looking for, but the elect did find it. The rest were hardened,

I ask, then, have they stumbled in order to fall? Absolutely not! On the contrary, by their stumbling, salvation has come to the Gentiles to make Israel jealous.

So that you will not be conceited, brothers, I do not want you to be unaware of this mystery: A partial hardening has come to Israel until the full number of the Gentiles has come in.

And in this way all Israel will be saved, as it is written:

The Liberator will come from Zion;
He will turn away godlessness from Jacob.
