Meaning
When Aristarchus attached himself to Paul we do not know, but he seems ever after the Ephesian uproar to have remained in Paul's company. He was one of those who accompanied Paul from Greece via Macedonia (Ac 20:4). Having preceded Paul to Troas, where they waited for him, they traveled with him to Palestine. He is next mentioned as accompanying Paul to Rome (Ac 27:2). There he attended Paul and shared his imprisonment. He is mentioned in two of the letters of the Roman captivity, in the Epistle to the church at Col 4:10, and in the Epistle to Phm (Phm 1:24), in both of which he sends greetings. In the former Paul calls him "my fellow-prisoner." According to tradition he was martyred during the persecution of Nero.
