The Prophet concludes the subject which he has been hitherto pursuing. He says that the Chaldeans would not come to engage in a doubtful war, but only to triumph over conquered nations. We indeed know that the Jews, though not excelling either in number or in riches, were yet so proud, that they looked down, as it were, with contempt on other nations, and we also know, that they vainly trusted in vain helps; for as they were in confederacy with the Egyptians, they thought themselves to be beyond the reach of danger. Hence the Prophet says, that kings and princes would be only a sport to the Chaldeans, and their fortresses would be only a derision to them. How so? For they will gather dust, he says; that is, will make a mound of the dust of the earth, and will thus penetrate into all fortified cities.
