A colloquial summary
Chpt 8: With Uriah and Zechariah as witnesses, Isaiah made a sign that said, “Future Property of Assyria,” referring to Syria and Israel. Soon, his wife, a prophetess became pregnant with a son. Isaiah named him, “The Assyrians,” in reference to the prophecy he wrote on the sign, which would be fulfilled before the child was able to properly form a sentence.
God reiterated that the Assyrians would flood the land like the Euphrates River overrunning its banks—and resistance is futile. God clearly told Isaiah not to buy into the conspiracy theories that work people into a frenzy, but to fear and dread Him only. For His true people, He will be a stone fortress. For the rest, a stumbling stone. The law of God will be entrusted to His few remaining people, of which Isaiah and his family are symbolic. People will get so hard up for leadership and direction that they will consult the dead. God’s law will be there all along, but they won’t understand it. Instead they’ll persist in their doomsday pessimism and eventually be taken captive.
Chpt 9: But there is mercy for those who have trusted in God through the difficulties. A child related to King David will usher in a new era—the day of the underdog. His coming signals a new order, an ever-expanding kingdom marked by perpetual peace and justice. God has already issued sentence for those who have disgraced His name (claiming to be His people). They are the very ones who said, “We can just rebuild on the ruins.” God is mustering an army to encompass them. Even so, they won’t humble themselves before Him. So He will cut off the tail that wags the dog and the head of the dog too! Religious leaders and politicians alike have been misleading the people. There will be no mercy, not for them, not for the people they have mislead—not even the young men, women or children. All will be fuel for the fire. And they will push each other into the fire to try to save their own lives for a moment more. Such a bloodthirsty people. And God’s not done yet…
