Romans 16:9

Οὐρβανὸν. “A common slave name, found among the members of the (imperial) household,” S. H. The name of course tells us nothing as to nationality. He may have been a Jew or a Greek.

τὸν συνεργὸν ἡμῶν. Prob., as S. H., a general description of working in the same cause as S. Paul and his companions, not necessarily of personal fellowship; cf. Philemon 1:1 only: elsewhere always μου (Romans 16:3; Romans 16:21; Philippians 2:25; Philippians 4:3; 2 Corinthians 8:23 (ἐμὸς); Philemon 1:24).

Στάχυν. “Rare but found in the imperial household,” S. H.; cf. Witkowski, Ep. Priv., p. 73.
