Alexander the coppersmith (Αλεξανδρος ο χαλκευς). Old word, only here in N.T., for metal-worker (copper, iron, gold, etc.). Possibly the one in 2. Timothy 1:20, but not the one in Acts 19:33 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 2. Timothy 4:8, but with a very different atmosphere.
