2-timothy 4:20

Erastus abode at Corinth - He was treasurer of that city, as we learn from Romans 16:23 (note). The apostle had sent him and Timothy on a mission to Macedonia, Acts 19:22, whence it is probable he returned to Corinth, and there became finally settled.

Trophimus have I left at Miletum sick - Even the apostles could not work miracles when they pleased; that power was but rarely given, and that for very special purposes. Trophimus was an Ephesian. See Acts 20:4, and the note there.

Miletus was a maritime town of Ionia, not far from Ephesus; but there was another Miletus, in Crete, which some learned men think to be intended here. It appears that St. Paul went from Macedonia to Corinth, where he left Erastus; from Corinth he proceeded to Troas, where he lodged with Carpus: from Troas he went to Ephesus, where he visited Timothy; from Ephesus he went to Miletus, where he left Trophimus sick; and having embarked at Miletus, he went by sea to Rome. See Calmet. It is most likely, therefore, that the Miletus of Ionia is the place intended.

Erastus - see the notes on Romans 16:23.

Abode at Corinth - This was his home, where he filled an important office; see the notes at Romans 16:23. It would seem that when Paul went to Rome, there was some expectation that he would accompany him, but that reasons had occurred for his remaining in Corinth. His doing so is referred to without blame.

But Trophimus - see Acts 20:4. He was a native of Asia Minor.

Have I left at Miletum sick - Probably he designed to accompany him to Rome, as he had been often with him in his journeys. On the situation of Miletus, or Miletum, see the notes on Acts 20:15.

4:20 When I came on, Erastus abode at Corinth - Being chamberlain of the city, Romans 16:23 .But Trophimus I have left sick - Not having power (as neither had any of the apostles) to work miracles when he pleased, but only when God pleased.
