Because Isaiah’s Seven-Part Synchronous Structure converts the entire Book of Isaiah into an end-time prophecy, ancient Assyria’s conquest of the then-known world foreshadows a similar world conquest by an end-time “Assyria.” Assyria’s brutal subjugation of nations and peoples includes the destruction of their defenses and infrastructure. As occurred anciently, an alliance of evil world powers rallies to end-time Assyria’s standard to accomplish the task of conquering the world. When its king figure has served God’s purpose of punishing its unrepentant inhabitants, he himself is punished.
Isaiah 13:4–5Hark! A tumult on the mountains, as of a vast multitude. Hark! An uproar among kingdoms, as of nations assembling: Jehovah of Hosts is marshaling an army for war. They come from a distant land beyond the horizon— Jehovah and the instruments of his wrath — to cause destruction throughout the earth.
Isaiah 10:12–14But when my Lord has fully accomplished his work in Mount Zion and in Jerusalem, he will punish the king of Assyria for his notorious boasting and infamous conceit, because he said, I have done it by my own ability and shrewdness, for I am ingenious. I have done away with the borders of nations, I have ravaged their reserves, I have vastly reduced the inhabitants. I have impounded the wealth of peoples like a nest, and I have gathered up the whole world as one gathers abandoned eggs; not one flapped its wings, or opened its mouth to utter a peep.
Isaiah 37:24–27You thought, On account of my vast chariotry I have conquered the highest mountains, the farthest reaches of Lebanon. I have felled its tallest cedars, its choicest cypresses. I have reached its loftiest summit, its finest forest. I have dug wells and drunk of foreign waters. With the soles of my feet I have dried up all Egypt’s rivers! Have you not heard how I ordained this thing long ago, how in days of old I planned it? Now I have brought it to pass. You were destined to demolish fortified cities, [turning them] into heaps of rubble, while their timorous inhabitants shrank away in confusion, becoming as wild grass, transiently green, or like weeds on a roof that scorch before they grow up.
