Isa. xix. 1.  “Behold, the Lord rideth upon a swift cloud, and cometh unto Egypt:  and the idols of Egypt shall be moved at His presence.”  The prophecy was supposed by many of the Fathers to have been fulfilled by the flight into Egypt.  Cf. Athanas. (Ep. LXI. ad Maximum, § 4):  “As a child He came down to Egypt, and brought to nought its idols made with hands:”  and (de Incarn. § 36):  “Which of the righteous men or kings went down into Egypt, so that at his coming the idols of Egypt fell?”  On the passage of Isaiah see Delitzsch, and Kay (Speaker’s Commentary).
