Hebrews 13:23

“Know ye that [our] brother Timothy is set at liberty, etc..] This is the same person to whom the Apostle Paul wrote two epistles, and whom he often calls his son, though sometimes his brother, as here, (<510101>Colossians 1:1 <520302>1 Thessalonians 3:2) of him he says, that he was set at liberty, or “dismissed”; either by the apostle, by whom he was sent into some parts, upon some business; or rather was loosed from his bonds, having been a prisoner for the sake of Christ and the Gospel; and, it may be; a fellow prisoner with the apostle, at Rome, as Aristarchus and others were; and this very great and useful person being known, very likely, to the Hebrews, since his mother was a Jewess,…”

On the meaning of this, and its importance in determining who was the author of the Epistle, see the Introduction section 3, (5) 4, and Prof. Stuart’s Introduction, section 19. This is a strong circumstance showing that Paul was the author of the Epistle, for from the first acquaintance of Timothy with Paul he is represented as his constant companion, and spoken of as a brother; 2 Corinthians 1:1 note; Philippians 1:1 note; Colossians 1:1 note; Philippians 1:0 note. There is no other one of the apostles who would so naturally have used this term respecting Timothy, and this…”

“If he come - To me. Hebrews 13:25”

“13:23 This Timothy may have been Paul’s traveling companion (see “Timothy” Profile); if so, his imprisonment is not mentioned elsewhere in the New Testament. He clearly knows the author and the recipients of this letter.”

“brother: Act 16:1-3; Th1 3:2; Plm 1:1 is set: Ti1 6:12; Ti2 1:8; Rev 7:14 I will: Rom 15:25, Rom 15:28; Plm 1:22 Hebrews 13:24”
