With Onesimus - Who had been formerly a servant of Philemon, an inhabitant of Colossae; see the notes at Plm 1:10. Onesimus had probably been recently converted; and Paul felt toward him the warm attachment of a brother; Plm 1:16. In what way he became acquainted with him is unknown. A more full account of him will be found in the notes at the Epistle to Philemon.
Who is one of you - That is, either who is from your city, or one of your own people and nation. It is clear from this, that Onesimus was from Phrygia, and probably from the city of Colossae itself. It would seem also that he was of a higher rank than is designated by the word "slave" now. He was, indeed, a "servant" δοῦλος doulos - of Philemon, but would the apostle have addressed the Colossians, and said that he was "one of them," if he had occupied precisely the condition which is now denoted by the word "slave"? Would a minister of the gospel now in the Northern States, who should send a letter by a run-away slave to a community of masters at the South, say of him that he was "one of them?" Would it be kindly received, or produce a good impression, if he did? There is reason, therefore, to think that Onesimus was not a slave in the proper sense, but that he might have been a respectable youth, who had bound himself to service for a term of years; compare Plm 1:18.
They shall make known to you all things which are done here - Relating to Paul himself and the state of the church in Rome. As the Epistle which Paul sent was designed not only for them, but to be a part of the volume of revealed truth, he wrote only those things which would be of permanent interest. Other matters he left for those who carried the Epistle to communicate. It would also serve to give Tychicus and Onesimus more respectability in view of the church at Colossae, if he referred the church to them for information on important points.

With Onesimus - who is one of you - Onesimus was a native of some part of Phrygia, if not of Colosse itself; and being lately converted to the Christian faith by the instrumentality of the apostle, he would be able, on this account, to give them satisfactory information concerning the apostle's state, which would be doubly acceptable to them as he was their countryman. See the Epistle to Philemon.
All things which are done here - FG, the Vulgate, Itala, Jerome, and Bede, add here πραττομενα, what is done, which we have supplied in Italics in our translation. These brethren could give an account of the transactions at Rome, relative to the apostle and Christianity, which it might not be prudent for him to commit to writing. See on Colossians 4:7 (note). The reign of Nero was not only cruel, but suspicious, jealous, and dangerous.

With Onesimus,.... Who had been Philemon's servant, ran away from him, and was met with and converted by the Apostle Paul, of whom he says many things in his epistle to his master. According to the Apostolic Constitutions, he was afterwards bishop of Beyrhoea; and some say he suffered martyrdom under Domitian; a servant of this name is mentioned by Suetonius (i), Ignatius (k) speaks of one Onesimus as bishop of Ephesus, but not the same with this,
a faithful and beloved brother, who is one of you; either one of their ministers, as Epaphras was, Colossians 3:12 or one of their city, who was originally a native of that place; and which the apostle mentions, the more to recommend him; though this is the least part of his commendation; he calls him a "brother", being both a converted man, and in the ministry; and being faithful in his work to Christ, and greatly beloved, by the saints; and particularly highly in the esteem and affections of the apostle:
they shall make known unto you all things which are done here; at Rome, either to him in prison, or in the church; and being two of them, were a proper number to bear a testimony, and which ought to be received.
(i) ln Vit. Galbae, c. 13. (k) Ep. ad Ephes. p. 17. & ad Antioch. ascript. p. 89.

Onesimus--the slave mentioned in the Epistle to Philemon (Plm 1:10, Plm 1:16), "a brother beloved."
a faithful . . . brother--rather, "the faithful brother," he being known to the Colossians as the slave of Philemon, their fellow townsman and fellow Christian.
one of you--belonging to your city.
They shall make known unto you all things--Greek, "all the things here." This substantial repetition of "all my state shall Tychicus declare unto you," strongly favors the reading of English Version in Colossians 4:8, "that he might (may) know your state," as it is unlikely the same thing should be stated thrice.
