Joshua referred to Migdal-Gad, ‘tower of Gad’, one of the fortified cities of Judah, and also to Migdal-El, ‘tower of God’, a place in Palestine. Jeremiah referred to the Migdol of Egypt, an island in the Nile, and Ezekiel referred to the Migdol of Syene, in Upper Egypt, in the context of the seat of government. The Book of Exodus records that the children of Israel encamped at Pi-hahiroth between Migdol and the Red Sea, before their historic crossing. The migdol in that location was not a place name, but an elevated land mass between two river beds, rising to about 300 metres.
