Egypt as a symbol for the material world is very common in Gnosticism… The biblical story of Israel’s bondage and liberation lent itself admirably to spiritual interpretation of the type the Gnostics liked.
Jonas establishes Egypt as the Gnostic master-symbol for the material world, tracing the valence through Hebrew polemic, the death-cult associations of Egyptian religion, and the Gnostic redeployment of the Exodus narrative as allegory of pneumatic liberation.
