1 Corinthians 16:19

The churches of Asia salute you. Aquila and Prisca salute you much in the Lord, with the church that is in their house.

'churches of Asia' -such as Ephesus, Colossae and those mentioned in the book of Revelation. Paul's stay in Ephesus had resulted in the establishment of other congregations, besides the one at Ephesus. (Acts 19:10; Acts 19:26)

'Aquila and Prisca' -Who had first met Paul at Corinth. (Acts 18:1) When he had left Corinth, they left with him (Acts 18:18). They were still with him in Ephesus when this letter was written

'One of the interesting things about Aquila and Priscilla is that they show us how easy and natural travel was even at that time. These two followed their trade from Palestine to Rome, from Rome to Corinth, from Corinth to Ephesus, and from Ephesus back to Rome (Romans 16:3)' (Barclay pp. 186-187)

'salute you much in the Lord' -'send really warm greetings' (McGuiggan p. 218) 'salute you most heartily' (Ber)

'with the church that is in their house' -most think this refers to the Christians that met in their home. (Romans 16:5) But other passages seem to indicate that this expression could also refer to those members of the household who are Christians. (Colossians 4:15)
