Trophimus

In writing to Timothy, the apostle comments that he left Trophimus in Miletus due to illness.

[3] Trophimus was one of eight friends (Acts 20:4), who accompanied Paul at the close of his third missionary journey and traveled with him from Greece, through Macedonia, into Asia, and onward by sea until Jerusalem was reached.

The occasion of this outrage was that Paul had "brought Greeks also into the temple, and....defiled this holy place" (Acts 21:28).

This shows that he was again — several years after the date indicated in the previous passages — traveling with Paul on one of the missionary journeys which the apostle undertook after being liberated from his first imprisonment in Rome.

[6] Sopater the Berean, son of Pyrrhus, accompanied him; and of the Thessalonians, Aristarchus and Secundus; and Gaius of Derbe, and Timothy; and the Asians, Tychius and Trophimus.For they had previously seen Trophimus the Ephesian with him in the city, they supposed that Paul had brought him into the temple.Erastus remained at Corinth, and I left Trophimus, who was ill, at Miletus.
