The important city of Hierapolis is mentioned only once in the New Testament.
Epaphras, who is one of you . . . is working had for you and for those at Laodicea and Hierapolis.
(Colossians 4:12-13; NIV)
Epaphras evidently founded the churches at Colossae, Laodicea, and Hierapolis that are located in the Lycus Valley—possibly during the long stay of Paul at Ephesus. For a variety of reasons we would expect some type of Jewish presence in these cities.
Although actual synagogues have not been found (Colossae had not been excavated) a variety of menoroth (menorahs; seven branch candlesticks) have been found engraved on tombs, a sarcophagus, and a column indicating a Jewish presence in the area.
