IV. The use and application of this, v. 5, 6. 1. All that had any dependence upon, or correspondence with, Egypt and Ethiopia, should now be ashamed of them, and afraid of having any thing to do with them. Those countries that were in danger of being overrun by the Assyrians expected that Tirhakah, king of Ethiopia, with his numerous forces, would put a stop to the progress of their victorious arms, and be a barrier to his neighbours; and with yet more assurance they gloried that Egypt, a kingdom so famous for policy and prowess, would do their business, would oblige them to raise the siege of Ashdod and retire with precipitation. But, instead of this, by attempting to oppose the king of Assyria they did but expose themselves and make their country a prey to him. Hereupon all about them were ashamed that ever they promised themselves any advantage from two such weak and cowardly nations, and were more afraid now than ever they were of the growing greatness of the king of Assyria, before whom Egypt and Ethiopia proved but as briers and thorns put to stop a consuming fire, which do but make it burn the more strongly. Note, Those who make any creature their expectation and glory, and so put it in the place of God, will sooner or later be ashamed of it, and their disappointment in it will but increase their fear. See Ezek. xxix. 6, 7. 2. The Jews in particular should be convinced of their folly in resting upon such broken reeds, and should despair of any relief from them (v. 6): The inhabitants of this isle (the land of Judah, situated upon the sea, though not surrounded by it), of this country (so the margin); every one shall now have his eyes opened, and shall say, "Behold, such is our expectation, so vain, so foolish, and this is that which it will come to. We have fled for help to the Egyptians and Ethiopians, and have hoped by them to be delivered from the king of Assyria; but, now that they are broken thus, how shall we escape, that are not able to bring such armies into the field as they did?" Note, (1.) Those that confide in creatures will be disappointed, and will be made ashamed of their confidence; for vain is the help of man, and in vain is salvation hoped for from the hills or the height and multitude of the mountains. (2.) Disappointment in creature confidences, instead of driving us to despair, as here (how shall we escape?), should drive us to God; for, if we flee to him for help, our expectation shall not be frustrated.
