Romans 15:7-10

Therefore, [continue to] accept and welcome one another, just as Christ has accepted and welcomed us to the glory of [our great] God. For I tell you that Christ has become a servant and a minister to the circumcision (Jews) on behalf of God’s truth, to confirm and verify the promises made to the fathers, and for the Gentiles to glorify God for His mercy [to them, since God had no covenant with them]. As it is written and forever remains written, “THEREFORE I PRAISE YOU AMONG THE GENTILES, AND SING PRAISES TO YOUR NAME.” [Ps 18:49] Again it says, “REJOICE and CELEBRATE, O GENTILES, ALONG WITH HIS PEOPLE.” [Deut 32:43]
