16:3 Greet Priscilla and Aquila. These active fellow-workers had first aided Paul at Corinth (Ac 18:2); then they went to Ephesus, and prepared the way for his work there (Ac 18:26); they had now returned to Rome, their former home. Some have argued that this greeting could not have been sent to Rome, from the fact that Paul had left them at Ephesus. It was the natural thing for them to go back home, when they could safely do so, and Godet says that from two or three years had passed since Paul left them at Ephesus, which gives ample time for a change of residence. The fact that the name of the wife comes first here, and in Ac 18:2, seems to imply that she was the more efficient. They are also named in 1Co 16:19 2Ti 4:19.
16:1-16 Paul recommends Phebe to the Christians at Rome. It becomes Christians to help one another in their affairs, especially strangers; we know not what help we may need ourselves. Paul asks help for one that had been helpful to many; he that watereth shall be watered also himself. Though the care of all the churches came upon him daily, yet he could remember many persons, and send salutations to each, with particular characters of them, and express concern for them. Lest any should feel themselves hurt, as if Paul had forgotten them, he sends his remembrances to the rest, as brethren and saints, though not named. He adds, in the close, a general salutation to them all, in the name of the churches of Christ.
