Romans 15
8 Ref Now I say that Christ has been made a servant of the circumcision to give effect to the undertakings given by God to the fathers,
9 Ref And so that the Gentiles might give glory to God for his mercy; as it is said, For this reason I will give praise to you among the Gentiles, and I will make a song to your name.
10 Ref And again he says, Take part, you Gentiles, in the joy of his people.
