A.T. Robertson Commentary 2 Timothy 4:14

"Alexander the coppersmith did me much evil: the Lord will render to him according to his works:" — 2 Timothy 4:14 (ASV)

Alexander the coppersmith (Αλεξανδρος ο χαλκευς). Old word, only here in N.T., for metal-worker (copper, iron, gold, etc.). Possibly the one in 1:20, but not the one in Ac 19:33f. unless he afterwards became a Christian.

Did me much evil (μο κακα ενεδειξατο). Evidently he had some personal dislike towards Paul and possibly also he was a Gnostic.

Will render (αποδωσε). Future active of the same verb used in verse 8, but with a very different atmosphere.
