John Wesley on Isaiah 52:4

Egypt - Where they had protection and sustenance, and therefore owed subjection to the king of Egypt. And yet when he oppressed them, I punished him severely, and delivered them out of his hands. The Assyrian - The king of Babylon, who is called the king of Assyria, 2Kings 23:29, as also the Persian emperor is called, Ezra 6:22, because it was one and the same empire which was possessed, first by the Assyrians, then by the Babylonians, and afterwards by the Persians. Without cause - Without any such ground or colour, by mere force invading their land, and carrying them away into captivity.
