2 Timothy 4:20

Erastus abode -Stayed at his post"; the verb suggests certainly that he had been commissioned by St Paul for some duty which he courageously fulfilled; if therefore it is unlikely that the Erastus who was chamberlain or treasurer (Oeconomus) of Corinth could be a fellow minister with Timothy to Macedonia (Acts 19:22), it is equally unlikely that he could have been set on dutyat Corinth, as is implied here. In which case we may identify the Erastus of Acts 19:22 with the Erastus here, and regard the -chamberlain" as a different person. See sketch of last journeys of St Paul and his companions in the Introduction, p. 43.

Trophimus An Ephesian and Gentile, who was with St Paul at Troas on the third missionary journey (Acts 20:4) and accompanied him to Jerusalem, causing a disturbance there because he was a Gentile (Acts 21:29). The only natural way of placing this event is at some visit to Miletus after the close of the Acts, see Introduction, p. 43. Miletummust be a misprint of A.V. as there is no authority anywhere for a neuter form.
