Adam Clarke's Commentary on the Bible

Verse 13 (2 Timothy 3:13)

Evil men and seducers shall wax worse - They will yet get on for a season, deceiving themselves and deceiving others; but, by and by, their folly will become manifest to all, 2 Timothy 3:9 . The word γοητες , which we render seducers, signifies jugglers, pretenders to magical arts; probably persons dealing in false miracles, with whom the Church in all ages has been not a little disgraced.
