Romans 15:8-10

ASV(i) 8 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, 9 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.
10 And again he saith,
Rejoice, ye Gentiles, with his people.
