2 Timothy 3:8
Jannes and Jambres.. Names not mentioned in the O.T. Exodus 7:11, but in other literature (Josephus) magicians who opposed Moses.
Reprobate .. RSV "counterfeit" (coins) that which does not stand the test, and so rejected. (8x) also castaway, rejected.
Point: Is Paul identifying Hymenaeus and Philetus with sin of seducing people with magical practices. Ephesus was a center of such magic, Acts 13:8 Acts 13:10 Acts 19:19 See "seducers" in 2 Timothy 3:13 also.
