Erastus abode at Corinth. — Better rendered, remained at Corinth. An Erastus is mentioned in Romans 16:23, the “chamberlain” of Corinth, one of the Christian congregation of that city. This man was probably identical with him.
Another “Eastus” appears among those who ministered to St. Paul at Ephesus (Acts 19:22). Him St. Paul sent on missionary work into Macedonia. There were, therefore, among St. Paul’s friends two men of this name: the one a resident official personage at Corinth; the other one of that band who journeyed hither and thither for the propagation of the faith.
But Trophimus have I left at Miletum sick. — Trophimus, a Gentile Christian, who was with St. Paul on his third missionary journey, and whom the Apostle was accused of taking into the Temple at Jerusalem. It was this accusation on the part of the Jews which led to St. Paul’s arrest which preceded his first long imprisonment. The event here alluded to must have taken place some time after the Apostle’s release from the first imprisonment, A.D. 63, and, probably, in the course of his last journey, shortly before his second arrest and imprisonment at Rome, about A.D. 66.
Miletus (not “Miletum”), a seaport of Caria, about thirty miles from Ephesus, once a city of great renown, whence, it is said, eighty colonies had proceeded; but in the days of St. Paul its glories were already on the wane. It is now famous only for its vast ruined theatre. (See Acts 20:15.)
It has been suggested that this mention of Trophimus was intended to clear him of any neglect. “Erastus,” wrote the Apostle, “remained at Corinth; but Trophimus’ reason for not coming to Rome was his sickness.”
