Morish
Fellow labourer with Paul, and called 'the beloved physician.' He is only three times mentioned by name. Col 4:14; 2Ti 4:11; Phm 1:24. He was the writer of the Gospel bearing his name, and also of the Acts of the Apostles, the introduction to both being addressed to a certain Theophilus. It is supposed, from Col 4:11,14, that he was a Gentile, though these verses are no proof of it.
In Ac 16:10 Luke uses the word 'we,' showing that he was then with the apostle Paul at Troas, and accompanied him to Philippi, where apparently Luke remained. In Ac 20:5 he is again with Paul, and went with him to Jerusalem. Paul then became a prisoner for more than two years, and we lose sight of Luke; but as soon as Paul was about to be sent to Rome, Luke was with him again, Ac 27:1, and accompanied him to Rome, Ac 28:16, and was there with Paul when he wrote the Epistles to the Colossians and Philemon. He was also with Paul during his second imprisonment. Others had forsaken the aged apostle, Luke alone remained. He was Paul's beloved fellow-labourer, and in his own writings has skilfully hidden himself that the work of God by His servants Paul and others might, by the leading of the Holy Spirit, be faithfully recorded, and come into prominence.
