A.T. Robertson Commentary Romans 10:12

"For there is no distinction between Jew and Greek: for the same [Lord] is Lord of all, and is rich unto all that call upon him:" — Romans 10:12 (ASV)

Distinction (διαστολη). See on this word 3:22. Here it is followed by the ablative case Ιουδαιου τε κα Hελληνος (between Jew and Greek).

Lord of all (Κυριος παντων). See Ga 3:28.

Rich (πλουτων). Present active participle of πλουτεω. See Eph 3:8 "the unsearchable riches of Christ."
