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 - Proconsular Asia. 'all there now, when they were in Rome (not "be" but) turned from me' then: "ashamed of my chain," in contrast to Onesiphorus: did not stand with me, but forsook me (2 Timothy 4:16). Possibly the occasion was at his apprehension in Nicopolis, where they had escorted him on his way to Rome, but from which they turned back to Asia. An inspiriting call to Timothy, as being his "son" (2 Timothy 2:1) now in Asia, like Onesiphorus, to make up for their defection, and to come to him (2 Timothy 4:21).
Phygellus and Hermogenes specified perhaps as persons from whom such cowardice could least be Phygellus and Hermogenes - specified, perhaps, as persons from whom such cowardice could least be expected; or, as well known to Timothy, and spoken of in conversations between him and Paul when the latter was in Asia.
