5th Sorrow & Joy of St. Joseph
In antiquity, Egypt represents what man can do without the God of Abraham, Issac, and Jacob. Joseph takes the Holy Family into Egypt - not only for protection - so that the True Saviour may turn his back on the false idols of the land.
5th Sorrow: The flight into Egypt (Matthew 2:14)
5th Joy: The overthrow of the idols of Egypt (Isaiah 19:1)
