Matthew Poole and continuators on 2 Timothy 1:15

15 This thou knowest that all they which are in Asia be turned away from me , of whom are Phygellus and Hermogenes .

Probably as to some he had a personal knowledge of their Apostacy, as to others he knew it by information, which Paul confirmeth.

It seemeth unreasonable to interpret all here of every individual, but many (as all oft signifieth in Holy Writ:) Some interpret it of all the Jewish Proselytes, others of those of Asia, who accompanied Paul to Rome, and there seeing his sufferings Apostatised, others of many who still abode in Asia, where Timothy now was; these all, or many of them, deserted Paul, either wholly casting off the Christian profession, or withdrawing themselves from communion with Paul, when they saw him a Prisoner.

Of these two we have no more said in Holy Writ, and therefore can assert nothing of them with any certainty.
