It is not as though the word of God had failed. For not all those who are descended from Israel are truly Israel, ¹ 

And Isaiah cries out on behalf of Israel, “Though the number of the children ¹  of Israel are as the sand of the sea, only the remnant will be saved,

but Israel even though pursuing ¹  a law of righteousness ²  did not attain it. ³ 

But again I ask, didn’t Israel understand? ¹  First Moses says, “I will make you jealous by those who are not a nation; with a senseless nation I will provoke you to anger.” ² 

But about Israel he says, “All day long I held out my hands to this disobedient and stubborn people!” ¹ 

What then? Israel failed to obtain what it was diligently seeking, but the elect obtained it. The ¹  rest were hardened,

And so ¹  all Israel will be saved, as it is written: “The Deliverer will come out of Zion; he will remove ungodliness from Jacob.

God has not rejected his people whom he foreknew! Do you not know what the scripture says about Elijah, how he pleads with God against Israel?

For I do not want you to be ignorant of this mystery, brothers and sisters, ¹  so that you may not be conceited: A partial hardening has happened to Israel ²  until the full number ³  of the Gentiles has come in.
