Isaiah 20 - G. Campbell Morgan's Exposition on the Whole Bible

Yet the prophet sees hope even for Egypt. He describes the process. The result of the judgment will be fear, and in the case of a part of Egypt at least this will issue in submission to Jehovah. Where this is so, there will be healing, and the prophet finally sees both Egypt and Assyria joined in the worship of Jehovah, and ultimately a triple alliance of Israel, Egypt, and Assyria will be made a blessing in the midst of the earth. From that vision of hope for Egypt he turns to pronouncing against her the doom that is at hand.
