Romans 15:8-12

Now I say that Jesus Christ has become a servant to the circumcision for the truth of God, to confirm the promises made to the fathers, and that the Gentiles might glorify God for His mercy, as it is written: “For this reason I will confess to You among the Gentiles, And sing to Your name.” And again he says: “Rejoice, O Gentiles, with His people!” And again: “Praise the LORD, all you Gentiles! Laud Him, all you peoples!” And again, Isaiah says: “There shall be a root of Jesse; And He who shall rise to reign over the Gentiles, In Him the Gentiles shall hope.”
