Rom 15:8-12

8For I tell you that Christ has become a servant of the circumcised on behalf of the truth of God in order that he might confirm the promises given to the patriarchs,9and in order that the Gentiles might glorify God for his mercy. As it is written, “Therefore I will confess you among the Gentiles, and sing praises to your name”;10and again he says, “Rejoice, O Gentiles, with his people”;11and again, “Praise the Lord, all you Gentiles, and let all the peoples praise him”;12and again Isaiah says, “The root of Jesse shall come, the one who rises to rule the Gentiles; in him the Gentiles shall hope.”
