What does 2 Timothy 4:20 mean?
These final verses of 2 Timothy serve as a post-script. Paul is offering various greetings and messages. Here, he mentions Erastus, who "remained at Corinth." Timothy and Erastus had known each other for some time and had served in Macedonia together (Acts 19:22). Erastus was called a "city treasurer" in Corinth in Romans 16:23. This would be consistent with this verse that notes he "remained" at Corinth.Trophimus is also mentioned in Acts 20:4 and 21:29. He was an Ephesian Christian (Acts 21:29) who served with Paul in ministry, taking gifts to the poor believers in Jerusalem together before Paul's arrest there. In this verse he is noted as being "ill" with some unknown sickness and staying at Miletus. Miletus was a town near Ephesus where an early Christian community existed (Acts 20:15, 17). Trophimus had served at least some time with Paul shortly before his second Roman imprisonment, though where and for how long is uncertain.
