Joseph and Aseneth or Asenath is an ancient apocryphal expansion of the Book of Genesis's account of the patriarch Joseph's marriage to Aseneth.
According to Genesis 41:45, Pharaoh gives Aseneth, the daughter of Potipherah (Pentephres in the Septuagint) priest of On to Joseph as a wife. Genesis 41:50-52 narrates that Aseneth bore Joseph two sons Manasseh and Ephraim. No more is said of her. Like many narratives in Genesis, the biblical story is tantalizingly brief, and raises questions that were to fascinate later interpreters. Why would an upstanding descendant of Jacob (Israel) marry the daughter of a pagan priest, and how could it be justifiable? How could two of the eponymous tribes (the Tribe of Manasseh and the Tribe of Ephraim) be descended from a union with an outsider, otherwise prohibited by the Mosaic_law? The story of Joseph and Aseneth sets out to answer some of those questions.
The twenty-nine chapters of Joseph and Aseneth narrate the transformation of Aseneth, from idolatry to monotheism and the worship of Adonai. Aseneth, a virgin who has rejected numerous worthy suitors, falls in love with Joseph when he, as vizier of Egypt, visits her father. Joseph, however, rejects her as an unworthy idol worshipper.
Aseneth then secludes herself in her tower, repents of her idolatry, confesses her sin, and embraces Joseph's God. Begging for God's acceptance, she then receives an angelic visitor (looking like Joseph), who assures her that her prayers are answered and that she is now a new creation. There follows a strange and extended ritual, where in order to confer on her immortality, the angel shares with Aseneth a magical honeycomb, and is told of her heavenly counterpart Metanoia (Repentance).
