An oracle concerning Egypt. Behold, the LORD is riding on a swift cloud and comes to Egypt; and the idols of Egypt will tremble at his presence, and the heart of the Egyptians will melt within them.
Isaiah 19:1 ESV

Egypt (mitzrayim) literally refers to Egypt, but it is also a metaphor of the world apart from Israel. Try reading this prophecy in that light and see if it speaks on both levels.

“Cloud” (ab) implies a dark storm cloud. It’s the same word translated as “thick cloud” in Exodus 19:9 ESV when God meets Moses on Sinai. God's presence is often accompanied by clouds, smoke, darkness, and fire.
