Romans 15:9-14

and that the Gentiles might glorify God for his mercy; as it is written, For this cause I will confess to thee among the Gentiles, And sing unto thy name. And again he saith, Rejoice, ye Gentiles, with his people. And again, Praise the Lord, all ye Gentiles; And laud him, all ye people. And again, Esaias saith, There shall be a root of Jesse, And he that shall rise to reign over the Gentiles; In him shall the Gentiles trust. Now the God of hope fill you with all joy and peace in believing, that ye may abound in hope, through the power of the Holy Ghost. And I myself also am persuaded of you, my brethren, that ye also are full of goodness, filled with all knowledge, able also to admonish one another.
