What is meant by the covering of Judah, which in the beginning of this paragraph is said to be discovered, is not agreed. The fenced cities of Judah were a covering to the country; but these, being taken by the army of the Assyrians, ceased to be a shelter, so that the whole country lay exposed to be plundered. The weakness of Judah, its nakedness, and inability to keep itself, now appeared more than ever; and thus the covering of Judah was discovered. Its magazines and stores, which had been locked up, were now laid open for the public use. Dr. Lightfoot gives another sense of it, that by this distress into which Judah should be brought God would discover their covering (that is, uncloak their hypocrisy), would show all that was in their heart, as is said of Hezekiah upon another occasion, 2 Chron. xxxii. 31. Thus, by one means or other, the iniquity of Ephraim will be discovered and the sin of Samaria, Hos. vii. 1.
