A.T. Robertson Commentary Romans 1:14

"I am debtor both to Greeks and to Barbarians, both to the wise and to the foolish." — Romans 1:14 (ASV)

On debtor (οφειλετης) see Ga 5:3.

Both to Greeks and to Barbarians (Hελλησιν τε κα βαρβαροις). The whole human race from the Greek point of view, Jews coming under βαρβαροις. On this word see Ac 18:2,4; 1 Corinthians 4:11; Colossians 3:11 (only N.T. instances). The Greeks called all others barbarians and the Jews termed all others Gentiles. Did Paul consider the Romans as Greeks? They had absorbed the Greek language and culture.
