The next series of prophecies (chaps. 28-35) was apparently delivered in view of the approaching invasion of the Assyrians, by which the destruction of the kingdom of Israel was completed, and Judah was overrun and desolated; but which ended in the overthrow of the invading army, and the deliverance of Hezekiah and his kingdom.  The prophet denounces, first upon Ephraim and then upon Judah and Jerusalem, God’s heavy judgments for their iniquities, especially for the sin of making Egypt instead of Jehovah their confidence; foretells the utter and perpetual desolation of Edom, which here represents all the powers that array themselves in hostility against God’s people; and describes in glowing language the glory and peace of Zion under the future reign of the Messiah.

Next follows the history of Sennacherib’s invasion and overthrow; of Hezekiah’s sickness and miraculous recovery, and of his sin in connection with the mission of Merodach-baladan’s servants.  Chaps. 36-39.

In the second part of Isaiah, which includes the last twenty-seven chapters, the prophet is occupied with the future redemption and glory of Zion.  In the clear light of inspiration, and in accordance with the explicit prophecy that has just been quoted, he takes his stand in the future of Babylon’s supremacy, and of the captivity of Zion and the dispersion of her children; and he comforts the true Israel by the promise of restoration and elevation to a greater than the former glory, when all nations shall submit themselves to Jehovah, and shall minister to the peace and welfare of Zion.  If we divide these twenty-seven chapters into three equal sections of nine chapters each, the first and second close with the words:  “There is no peace, saith my God, to the wicked” (chaps. 48:22; 57:21); while the third ends with a more extended, threatening against the wicked (chap. 66:24).  The prominent characteristics of these three sections are thus given by Keil: 

“The first of these sections (chaps. 40-48) portrays the relation of Israel to the heathen nations; and from the redemption of Israel effected through Cyrus, the servant of God, it unfolds the certain victory of the Theocracy over the gods and powers of the heathen world.  The second section (chaps. 49-57) exhibits Israel as the seat of salvation for the world.  This it does by carrying out the thought that, just as Cyrus is to redeem Israel from the Babylonish captivity, so must the true servant of Jehovah, by his vicarious suffering and death, make expiation for sin, raise the covenant people to true glory, and make them, through the establishment of ‘the sure mercies of David’ (55:3), the centre of salvation for the whole world.  Finally in the third section (chaps. 58-66), after an exhortation in which the sins of the people are acknowledged and rebuked (chaps. 58, 59), the prophet foretells, in a series of majestic images, how the Theocracy shall be glorified when it shall become,
