Reflection on Isaiah 19:1 (ESV)

“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.”

All idolatry, rebellion, and unbelief will be judged. Salvation is only from the Lord. 
In Isaiah 19, the prophet Isaiah announces that judgment is coming against Egypt from the LORD. God is pictured as riding on a swift cloud. The gods of Egypt — of which there were many, would not be able to save their people from coming judgment. Their idols would tremble before Him, which would cause the people to be disheartened and depressed. They would realize that their gods, only mere idols, and their occult practices could not save them.

The final judgment upon Egypt comes in that day when the Lord appears in visible glory. Egypt will come, like other nations, to the front once more at the close of the times of the Gentiles. But mercy is also in store for Egypt. Egypt will be called “His people.” When the Lord smites Egypt that land will return to Him. It will then be lifted out of the dust and receive a place of blessing only second to that which Israel will enjoy.
