Alexander the coppersmith did me much evil: the Lord reward him according to his works:
Alexander the coppersmith - or 'smith,' some think. Perhaps the same as the Alexander (1 Timothy 1:20; note there) at Ephesus. Excommunicated then, he subsequently was restored, and now vented his malice, because of his excommunition, in accusing Paul before the Roman judges, whether of incendiarism or of introducing a new religion. See 'Introduction.' He may have been the Alexander put forward by the Jews in the tumult at Ephesus (Acts 19:33-34).
Reward. A C Delta G 'Aleph (') read 'shall reward' х apodoosei (G591) for apodoee]. Personal revenge certainly did not influence the apostle (2 Timothy 4:16, end: cf. Psalms 139:21).
