Romans 15:7-9

Wherefore receive ye one another, even as Christ also received you, to the glory of God. For I say that Christ hath been made a minister of the circumcision for the truth of God, that he might confirm the promises given unto the fathers, and that the Gentiles might glorify God for his mercy; as it is written, Therefore will I give praise unto thee among the Gentiles, And sing unto thy name.
