Epaphras (Greek: Ἐπαφράς) was an observer of the Apostle Paul mentioned twice in the New Testament epistle of Colossians and once in the New Testament letter to Philemon.
Douglas Moo, in his commentary about Colossians, writes this about Epaphras: "Little is known about him, though we can infer that he was a native of Colossae and that he was perhaps converted by Paul himself during the apostle's ministry in Ephesus. The mention of a co-worker at this point in a Pauline epistle is unusual, and the strength of Paul's endorsement of him is also striking (note also 4:12-13)."
