“Aristarchus my fellowprisoner saluteth you, and Marcus, sister's son to Barnabas, (touching whom ye received commandments: if he come unto you, receive him;)”
King James Version (KJV)
4:10 Aristarchus my fellowprisoner - Such was Epaphras likewise for a time, #Phm 1:23|. Ye have received directions - Namely, by Tychicus, bringing this letter. The ancients adapted their language to the time of reading the letter; not, as we do, to the time when it was written. It is not improbable, they might have scrupled to receive him, without this fresh direction, after he had left St. Paul, and departed from the work.
Col 4:10 There follow Christian remembrances from several of Paul's companions. Aristarchus, my fellow-prisoner. A Macedonian from Thessalonica (Ac 19:29 20:4 27:2). He accompanied Paul from Jerusalem to Rome. He is named in Phm 1:24. And Marcus. The old companion of Paul and Barnabas on their first missionary tour (Ac 13:5,13). Sister's son to Barnabas. It is now conceded that this should be, "Cousin to Barnabas". Since in this year (probably A.D. 62) Mark attends Paul, it is inferred that Barnabas was dead. Concerning whom. Mark. Commandments. Commendations. Receive him. Perhaps these churches knew that at one time Paul had refused to have Mark in his company (Ac 15:38), and hence would not have received him cordially without such a commendation.
