Easton's Bible Dictionary (1897)/Philemon
Philemon An inhabitant of Colosse, and apparently a person of some note among the citizens (Col. 4:9; Philemon 1:2). He was brought to a knowledge of the gospel through the instrumentality of Paul (19), and held a prominent place in the Christian community for his piety and beneficence (4-7). He is called in the epistle a "fellow-labourer," and therefore probably held some office in the church at Colosse; at all events, the title denotes that he took part in the work of spreading a knowledge of the gospel.
