ISB ~ Philemon 1 v1

Paul, a prisoner:Probably in Rome, where he lived for two years under house arrest (Acts 28:16-31). He was imprisoned, not for any crime, but for his commitment to Jesus Christ (Phil 1:13).

See introduction:Author and Date.

Timothy:A trusted companion of Paul and joint sender of several Pauline letters. See note on 1 Tim 1:2.

Philemon:The primary recipient of the letter. That Paul considers him a fellow worker suggests he is involved in Christian ministry (7).
