4:7 Tychicus. The primary carrier of the letters to the Colossians, Philemon, and the Ephesians (Eph. 6:21, 22). First mentioned as part of Paul’s entourage in Acts 20:4, Tychicus was from the Roman province of Asia (in modern Turkey), and appears to have been one of Paul’s more trusted emissaries toward the end of his ministry (2 Tim. 4:12; Titus 3:12).
