Jannes and Jambres, or sometimes Johanai and Mamre, or Iannes and Mambres, or Janis and Jamberes, are names given to the magicians who contended with Moses and Aaron and were discomfited by the Hebrew leaders in the Hebrew Bible Book of Exodus. These names were not given in the book of Exodus itself, but they appear in 2 Timothy 3:8 in the New Testament. Origen says that there was an apocryphal book called The Book of Jannes and Jambres, containing details of their exploits, and that St Paul's epistle was quoting from it. This book has not been rediscovered. Jannes and Jambres are mentioned in the Old Testament Targum Jonathan Exodus 7:11-8:19.
