John Gill Commentary 2 Timothy 4:19

"Salute Prisca and Aquila, and the house of Onesiphorus." — 2 Timothy 4:19 (ASV)

Salute Prisca and Aquila
The same with Priscilla and Aquila: and so the Complutensian edition, and some copies, read here; who were of the same occupation with the apostle, and with whom he wrought at Corinth, and whom he left at Ephesus; and who seem by this salutation to have continued there, (Acts 18:2Acts 18:3Acts 18:18Acts 18:19) .

And the household of Onesiphorus :
who also lived at Ephesus, and whose kindness to the apostle, when he was at Rome, is before mentioned, (2 Timothy 1:16–18) .
