Targums
Jannes and Jambres are mentioned in the Old Testament Targum Jonathan Exodus 7:11-8:19. Jewish traditions in the Targums preserve other half-legendary lore about the pair. They are called the sons of Balaam, the unwitting prophet of Peor. It was also claimed that they converted to Judaism, and that they left Egypt at the Exodus to accompany Moses and the Israelites; however, they perished on the way, either at the Red Sea, or the destruction of the Golden Calf, or at the slaughter of Korah and his followers.
