19:1-17 God shall come into Egypt with his judgments. He will raise up the causes of their destruction from among themselves. When ungodly men escape danger, they are apt to think themselves secure; but evil pursues sinners, and will speedily overtake them, except they repent. The Egyptians will be given over into the hand of one who shall rule them with rigour, as was shortly after fulfilled. The Egyptians were renowned for wisdom and science; yet the Lord would give them up to their own perverse schemes, and to quarrel, till their land would be brought by their contests to become an object of contempt and pity. He renders sinners afraid of those whom they have despised and oppressed; and the Lord of hosts will make the workers of iniquity a terror to themselves, and to each other; and every object around a terror to them.
4. cruel lord—"Sargon," in Hebrew it is lords; but plural is often used to express greatness, where, one alone is meant (Ge 39:2). The parallel word "king" (singular) proves it. Newton makes the general reference to be to Nebuchadnezzar, and a particular reference to Cambyses, son of Cyrus (who killed the Egyptian god, Apis), and Ochus, Persian conquerors of Egypt, noted for their "fierce cruelty." Gesenius refers it to Psammetichus, who had brought into Egypt Greek and other foreign mercenaries to subdue the other eleven princes of the dodecarchy.
