Some additional verses

As he also says in Hosea, “I will call those who were not my people, ‘My people,’ and those who were not loved, ‘Loved.’ And it will be in the place where it was said to them, ‘You are not my people,’ there they will be called ‘sons of the living God.’ ”
Acts 10:44–48While Peter was still speaking these words, the Holy Spirit fell on all those who were listening to the message. And those believers from the circumcision who had accompanied Peter were astonished that the gift of the Holy Spirit had been poured out even on the Gentiles, for they heard them speaking in tongues and glorifying God. Then Peter said, “Surely no one can withhold the water for these people to be baptized, who have received the Holy Spirit as we also did!” So he ordered that they be baptized in the name of Jesus Christ. Then they asked him to stay for several days.
Acts 11:18And when they heard these things, they became silent and praised God, saying, “Then God has granted the repentance leading to life to the Gentiles also!”
Acts 13:46–48Both Paul and Barnabas spoke boldly and said, “It was necessary that the word of God be spoken first to you, since you reject it and do not consider yourselves worthy of eternal life! Behold, we are turning to the Gentiles! For so the Lord has commanded us: ‘I have appointed you to be a light for the Gentiles, that you would bring salvation to the end of the earth.’ And when the Gentiles heard this, they began to rejoice and to glorify the word of the Lord. And all those who were designated for eternal life believed.
Eph 2:11–13Therefore remember that formerly you, the Gentiles in the flesh, the so-called uncircumcision by the so-called circumcision in the flesh, made by hands, that you were at that time apart from Christ, alienated from the citizenship of Israel, and strangers to the covenants of promise, not having hope, and without God in the world. But now in Christ Jesus you, the ones who once were far away, have become near by the blood of Christ.

Rom 11:11–12I say then, they did not stumble so that they fell, did they? May it never be! But by their trespass, salvation has come to the Gentiles, in order to provoke them to jealousy. And if their trespass means riches for the world and their loss means riches for the Gentiles, how much more will their fullness mean?
