The burden concerning Egypt. Behold, the LORD rides upon a swift cloud, and shall come into Egypt: and the idols of Egypt shall tremble at his presence, and the heart of Egypt shall melt in the midst of it.
All Commentaries on Isaiah 19:1 Go To Isaiah 19
Jerome
AD 420
We must think of that swift cloud as befitting either the body of the Savior, because his body was light, not weighted down by any sin; or certainly holy Mary, who was heavy with child by no human seed. Behold the Lord has entered the Egypt of this world on a swift cloud, the Virgin.
