5 Apphia is thought to be the wife of Philemon.
6 Most witnesses (D2 Ψ 𝔐) here read τῇ ἀγαπητῇ (tē agapētē, “beloved, dear”), a reading that appears to have been motivated by the masculine form of the same adjective in v. 1. Further, the earliest and best witnesses, along with a few others (א A D* F G I P 048 0278 33 81 104 1739 1881 ), have ἀδελφῇ (adelphē, “sister”). Thus on internal and external grounds, ἀδελφῇ is the strongly preferred reading.
7 Though the term “our” does not appear in the Greek text it is inserted to bring out the sense of the passage.
