Note 6 at 1Co 16:19: The book of Revelation was written to the seven churches of Asia. They were the church at Ephesus, the church at Smyrna, the church at Pergamos, the church at Thyatira, the church at Sardis, the church at Philadelphia, and the church at Laodicea (Re 2-3). The book of Acts only gives an account of Paul's ministry at one of these Asian churches, the church at Ephesus. However, Paul mentioned the church at Laodicea four times in his letter to the church at Colosse.

Note 7 at 1Co 16:19: Aquila and Priscilla first met Paul in Corinth. They accompanied Paul from Corinth to Ephesus and had a church that met in their house (see note 2 at Ac 18:2).
