acts 18:2 And found a certain Jew named Aquila, born in Pontus, lately come from Italy, with his wife Priscilla; (because that Claudius had commanded all Jews to depart from Rome:) and came unto them. - Free Bible Online

      2. a Jew . . . Aquila . . . with his wife Priscilla--From these Latin names one would conclude that they had resided so long in Rome as to lose their Jewish family names.
      born in Pontus--the most easterly province of Asia Minor, stretching along the southern shore of the Black Sea. From this province there were Jews at Jerusalem on the great Pentecost (Ac 2:9), and the Christians of it are included among "the strangers of the dispersion," to whom Peter addressed his first Epistle (1Pe 1:1). Whether this couple were converted before Paul made their acquaintance, commentators are much divided. They may have brought their Christianity with them from Rome [OLSHAUSEN], or Paul may have been drawn to them merely by like occupation, and, lodging with them, have been the instrument of their conversion [MEYER]. They appear to have been in good circumstances, and after travelling much, to have eventually settled at Ephesus. The Christian friendship now first formed continued warm and unbroken, and the highest testimony is once and again borne to them by the apostle.
      Claudius, &c.--This edict is almost certainly that mentioned by SUETONIUS, in his life of this emperor [Lives of the Cæsars, "Claudius," 25].
