J. B. Lightfoot on Colossians 4:9-10

^{10}Ἀσπάζεται ὑμᾶς Ἀρίσταρχος ὁ συναιχμάλωτός 10. The salutations to Philemon are sent from the same persons as to the Colossians, except that in the former case the name of Jesus Justus is omitted. Ἀρίσταρχος] the Thessalonian. He had started with St Paul on his voyage from Jerusalem to Rome, but probably had parted from the Apostle at Myra (see _Philippians_ p. 33 sq.). If so, he must have rejoined him at Rome at a later date. On this Aristarchus see _Philippians_ p. 10 and the introduction to the Epistles to the Thessalonians. He would be well known in proconsular Asia, which he had visited from time to time; Acts xix. 29, xx. 4, xxvii. 2. συναιχμάλωτός μου] In Philem. 23 this honourable title is withheld from Aristarchus and given to Epaphras. In Rom. xvi. 7 St Paul’s kinsmen, Andronicus and Junias, are so called. On the possibility of its referring to a spiritual captivity or subjection see _Philippians_ p. 11. In favour of this meaning it may be urged, that, though St Paul as a prisoner was truly a δέσμιος, he was not strictly an αἰχμάλωτος ‘a prisoner of war’; nor could he have called himself so, except by a confusion of the actual and metaphorical. If on the other hand συναιχμάλωτος refers to a physical captivity, it cannot easily be explained by any known fact. The incident in Acts xix. 29 is hardly adequate. The most probable solution would be, that his relations with St Paul in Rome excited suspicion and led to a temporary confinement. Another possible hypothesis is that he voluntarily shared the Apostle’s captivity by living with him. Μάρκος] doubtless John Mark, who had been associated with St Paul in his earlier missionary work; Acts xii. 25, xv. 37 sq. This commendatory notice is especially interesting as being the first mention of him since the separation some twelve years before, Acts xv. 39. In the later years of the Apostle’s life he entirely effaced the unfavourable impression left by his earlier desertion; 2 Tim. iv. 11 ἔστιν γάρ μοι εὔχρηστος εἰς διακονίαν. This notice is likewise important in two other respects. (1) Mark appears here as commended to a church of proconsular _Asia_, and intending to visit those parts. To the churches of this same region he sends a salutation in 1 Pet. v. 13; and in this district apparently also he is found some few years later than the present time, 2 Tim. iv. 11. (2) Mark is now residing at _Rome_. His connexion with the metropolis appears also from 1 Pet. v. 13, if Βαβυλῶν there (as seems most probable) be rightly interpreted of Rome; and early tradition speaks of his Gospel as having been written for the Romans (Iren. iii. 1. 1; comp. Papias in Euseb. _H.E._ iii. 39).
