This thou knowest, that all they which are in Asia be turned away from me; of whom are Phygellus and Hermogenes. All they which are in Asia - It seems as if the apostle must refer to the Asiatic Christians which were then at Rome, or had been lately there. Finding the apostle in disgrace, and thinking it dangerous to own him or his cause, they neither visited him, or confessed Christianity. He cannot be speaking of any general defection of the Asiatic Churches, but of those Asiatics who had professed a particular friendship for him.
Phygellus and Hermogenes - These were two of the persons of whom he complains; but who they were, or what office they held, or whether they were any thing but private Christians who had for a time ministered to St. Paul in prison, and, when they found the state determined to destroy him, ceased to acknowledge him, we cannot tell.
