Romans 15:8-11

For I say that the Messiah became a servant of the Jewish people in order to show God’s truthfulness by making good his promises to the Patriarchs,

and in order to show his mercy by causing the Gentiles to glorify God — as it is written in the Tanakh, “Because of this I will acknowledge you among the Gentiles and sing praise to your name.”

And again it says, “Gentiles, rejoice with his people.”
