In chapters 7-8 Isaiah tried to persuade King Ahaz to trust God in the face of the Syro-Ephraimitic threat against Judah. Ahaz refused to do so and instead turned to Assyria for help, with disastrous results. Ahaz's son, Hezekiah, faced a similar challenge during his reign, but this time the threat came from Assyria. Hezekiah learned from his father's failure and from Isaiah's preaching, made the right choice, and trusted the Lord. The result was deliverance. Thus chapters 36-37 contrast with chapters 7-8.
"Here we are presented with a historical test to demonstrate once and for all whether Jehovah is the one true God, the Sovereign over all the earth."346
". . . chapters 36-37 put the rock of history under the fabric of eschatology."347
"This is history at its best, no dull recital of statistics and dates but an account which enables us to sense the haughty arrogance of the Assyrian and the chilling clutch of despair at the hearts of the Israelites."348
