C. The tests of Israel's trust chs. 36-39

Chapters 36-39 conclude the section of the book dealing with the issue of trust by giving historical proof that Yahweh will protect those who trust in Him. In these chapters, King Hezekiah represents the people of Judah.³⁴⁴These lessons from history should encourage God's people to trust in Him rather than in the arm of flesh. Chapters 40-66 contain oracles in which Babylonian captivity looms large. So the present section (chs. 36-39) forms a bridge from emphasis on Assyria (chs. 1-35) to emphasis on Babylonia (chs 40-66). They are also almost identical to 2 Kings 18-20 (cf. 2 Chron. 29-32), except for the inclusion of Isaiah's poem in Isaiah 38:9-20.³⁴⁵These chapters consist of more narrative material and fewer oracles than the sections that precede and follow it, in which the opposite is true.

This section contains two parts. The first one (chs. 36-37) involved King Hezekiah's trust in God and deliverance when Sennacherib's Assyrian army besieged Jerusalem. The second (chs. 38-39) involved Hezekiah's failure to trust God and his consequent judgment by God when the Babylonian envoys peacefully visited Jerusalem. In chapters 36-37 we see Judah's deliverance accomplished, and in chapters 38-39 we hear Judah's captivity announced. Thus the real hinge of the book occurs between chapters 37 and 38, where emphasis on Assyria ends and emphasis on Babylonia begins.

 1. The Assyrian threat chs. 36-37

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

 2. The Babylonian threat chs. 38-39

The events in these chapters predate those in chapters 36-37 by a few months. Isaiah placed them here, out of chronological order, to make them a historical prologue to chapters 40-66, which focus on the Exile and the return to Jerusalem. This section opens with Hezekiah contemplating death (38:1a) and ends with him contemplating life (39:8). In between, Isaiah delivered two messages to the king (38:1b-7; 39:3-7) Hezekiah's dedication (38:8-22) followed the prophet's first message, and his defection (39:1-2), precipitated the second message. Thus the structure of these two chapters is chiastic.³⁷²
