Romans 1:14

I am a debtor both to the Greeks, and to the barbarians - It has been remarked before that all the nations of the earth, themselves excepted, were termed barbarians by the Greeks. See the origin of the word barbarous in the note on Acts 28:2 (note). The apostle considers himself, by his apostolical office and call, under obligation to preach the Gospel to all people, as far as the providence of God might open his way; for this is implied in the Divine commission: - Go ye into all the world, and preach the Gospel to every creature - to the wise and the unwise; to the learned and cultivated as well as to the unlearned and uncultivated. This evidently appears to be the import of the terms.
