Acts 21:29
29. Trophimus—(See on Ac 20:4).
Ephesians 6:21-22
21. that ye also—as I have been discussing things relating to you, so that ye also may know about me (compare Col 4:7, 8). NEANDER takes it, "Ye also," as well as the Colossians (Col 4:6).
my affairs—Greek, "the things concerning me." how I do—how I fare. Tychicus—an Asiatic, and so a fit messenger bearing the respective Epistles to Ephesus and Colosse (Ac 20:4; 2Ti 4:12). a beloved brother—Greek, "the beloved brother"; the same epithet as in Col 4:7. minister—that is, servant. in the Lord—in the Lord's work.22. for the same purpose—Greek, "for this very purpose." Col 4:8 is almost word for word the same as this verse.
our affairs—Greek, "the things concerning us," namely, concerning myself. "Aristarchus, my fellow prisoner, and Marcus, sister's son to Barnabas" (Col 4:10).Colossians 4:7-8
7. Tychicus—(See on Eph 6:2).
who is a beloved brother—rather, "the beloved brother"; the article "the" marks him as well known to them.8. for the same purpose—Greek, "for this very purpose."
that he might know your estate—Translate, "that he may know your state": answering to Col 4:7. So one very old manuscript and Vulgate read. But the oldest manuscripts and the old Latin versions, "that YE may know OUR state." However, the latter reading seems likely to have crept in from Eph 6:22. Paul was the more anxious to know the state of the Colossians, on account of the seductions to which they were exposed from false teachers; owing to which he had "great conflict for" them (Col 2:1). comfort your hearts—distressed as ye are by my imprisonment, as well as by your own trials.2 Timothy 4:12
12. And—Greek, "But." Thou art to come to me, but Tychicus I have sent to Ephesus to supply thy place (if thou so willest it) in presiding over the Church there in thy absence (compare Tit 3:12). It is possible Tychicus was the bearer of this Epistle, though the omission of "to thee" is rather against this view.
2 Timothy 4:20
20. In order to depict his desertion, he informs Timothy that Erastus, one of his usual companions (Ac 19:22, possibly the same Erastus as in Ro 16:23, though how he could leave his official duties for missionary journeys is not clear), stayed behind at Corinth, his native place, or usual residence, of which city he was "chamberlain," or city steward and treasurer (Ro 16:23); and Trophimus he left behind at Miletus sick. (On his former history, see on Ac 20:4; Ac 21:29). This verse is irreconcilable with the imprisonment from which he writes being the first: for he did not pass by Corinth or Miletus on his way to Rome when about to be imprisoned for the first time. As Miletus was near Ephesus, there is a presumption that Timothy was not at Ephesus when Paul wrote, or he would not need to inform Timothy of Trophimus lying sick in his immediate neighborhood. However, Trophimus may not have been still at Miletus at the time when Paul wrote, though he had left him there on his way to Rome. Prisca and Aquila were most likely to be at Ephesus (2Ti 4:19), and he desires Timothy to salute them: so also Onesiphorus' household (2Ti 1:18). Paul had not the power of healing at will (Ac 19:12), but as the Lord allowed him.
