Greet Priscilla and Aquila - This pious couple had been obliged to leave Rome, on the edict of Claudius, see Acts 18:2, and take refuge in Greece. It is likely that they returned to Rome at the death of Claudius, or whenever the decree was annulled. It seems they had greatly contributed to assist the apostle in his important labors. Instead of Priscilla, the principal MSS. and versions have Prisca, which most critics suppose to be the genuine reading.
Greet Priscilla and Aquila - Salute; implying the apostle‘s kind remembrance of them, and his wishes for their welfare.
Priscilla - Priscilla was the wife of Aquila. They are mentioned in Acts 18:2, Acts 18:26; 1 Corinthians 16:19. Paul at first found them at Corinth. Aquila was a Jew, born in Pontus, who had resided at Rome, and who had left Rome, and come to Corinth, when Claudius expelled the Jews from Rome; see the notes at Acts 18:2. It is probable that they were converted under the preaching of Paul. Paul lived with them, and they had the advantage of his private instruction; Acts 18:3; compare Acts 18:26. At the death of Claudius, or whenever the decree for the expulsion of the Jews was repealed, it is probable that they returned to Rome.
My helpers - My fellow-workers. They had aided him in his work. A particular instance is mentioned in Acts 18:26. They are mentioned as having been with Paul when he wrote the First Epistle to the Corinthians; 1 Corinthians 16:19.
In Christ Jesus - In the Christian cause.
