Asnat (אָסְנַת) is the Hebrew form of the Egyptian name Asenath, meaning "belonging to [the goddess] Neith" or "she belongs to her father." She was the daughter of Potiphera, priest of On (Heliopolis), whom Pharaoh gave to Joseph as his wife (Genesis 41:45). She became the mother of Ephraim and Manasseh.
The marriage of Joseph to Asenath, an Egyptian priest's daughter, represents one of Scripture's first instances of God incorporating Gentiles into the covenant story. Through this union came Ephraim and Manasseh — two of the twelve tribes of Israel. Jacob's blessing of these sons as his own (Genesis 48:5) formally incorporated Egyptian lineage into the covenant people. This foreshadows the radical inclusion of the nations in the New Covenant, where "there is neither Jew nor Gentile" (Galatians 3:28). God's redemptive purposes cannot be confined by ethnic boundaries.
