2 Timothy 4:12

“And Tychicus have I sent to Ephesus.] To supply the place of Timothy, while he came to Rome, and continued there: so careful was the apostle of the church there, that they might not be without the ministry of the word during his absence; (see <490620>Ephesians 6:20,21).”

“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.”

“And Tychicus - See Acts 20:4. In Ephesians 6:21, Paul calls him “a beloved brother, and faithful minister in the Lord.” But it may be asked why he did not retain him with him, or why should he have sent him away, and then call Timothy to him? The probability is, that he had sent him before he had seen reason to apprehend that he would be put to death; and now, feeling the need of a friend to be with him, he sent to Timothy, rather than to him, because Tychicus had been employed to perform some service which he could not well leave, and because Paul wished to give some some special instructions to Timothy before he died. Have I sent to Ephesus - Why, is not certainly known; compare Intro.…”

“4:12 Tychicus was apparently a Greek (implied in Col 4:7-8, 10-11) from Asia Minor (see also Acts 20:4; Eph 6:21-22; Col 4:7-8; Titus 3:12). He was possibly going to Ephesus to deliver the present letter and take over for Timothy (assuming that Timothy was in Ephesus; see study notes on 2 Tim 4:13, 19).”

“Tychicus: Act 20:4; Eph 6:21; Col 4:7; Tit 3:12 to: Act 20:16, Act 20:17, Act 20:25; Ti1 1:3 2 Timothy 4:13”
