The next promise in the prophecy is that they shall be my people and I will be their God..
This is applied here Rom 9:24-26
24Even us, whom he hath called, not of the Jews only, but also of the Gentiles?
25As he saith also in Osee, I will call them my people, which were not my people; and her beloved, which was not beloved.
26And it shall come to pass, that in the place where it was said unto them, Ye are not my people; there shall they be called the children of the living God.
This is the call of the Gentiles into Covenant Israel, the Church Eph 3:6
6That the Gentiles should be fellowheirs, and of the same body, and partakers of his promise in Christ by the gospel:
Eph 2:11-13
11Wherefore remember, that ye being in time past Gentiles in the flesh, who are called Uncircumcision by that which is called the Circumcision in the flesh made by hands;
12That at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world:
13But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ.
also 1 Pet 2:10
10Which in time past were not a people, but are now the people of God: which had not obtained mercy, but now have obtained mercy.
This too is another promise of the New Covenant which Christ is the Mediator of unto all whom He shed His blood for Heb 8:10
10For this is the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people:
So this Promise can be applied to the Church, the believers in Christ, the Israel of God, the spiritual seed of Abraham Gal 3:29
29And if ye be Christ's, then are ye Abraham's seed[Israel], and heirs according to the promise.69
