I. introduction chs. 1--5

The relationship of chapters 1-5 to Isaiah's call in chapter 6 is problematic. Do the first five chapters describe the prophet's ministry before he received his call--is the order chronological--or do they constitute an introduction to the anthology of prophecies that follow Isaiah's call--is the order literary? The commentators take both views. My preference is to view these prophecies not necessarily as the first ones Isaiah delivered in his ministry but as those he placed here to form an introduction to his whole book. They present in a succinct way the problem that the rest of the book solves. Isaiah's call (ch. 6) is the most concise statement of the solution, and the chapters after that one spell it out in more detail. Probably Isaiah, or whoever arranged these prophecies in their final form, put these prophecies here to set before the reader the situation facing Israel that Isaiah addressed in the rest of the book.

 A. Israel's condition and God's solution ch. 1

As chapters 1-5 introduce the whole book, so chapter 1 introduces the rest of the introduction to the book (chs. 2-5). It presents the situation in Judah in the second half of the eighth century and reveals God's will for His people. This chapter summarizes all Isaiah's characteristic and essential teachings. Judgment from the Lord had to come on the people of Judah because they had sinned against Him. This judgment would purify and perfect them because God had a future for them. God's indictment of His people is similar to a covenant lawsuit.

 B. The problem with Israel chs. 2-4

This second major segment of the introduction to the book (chs. 1-5) contrasts what God intended Israel to be (2:1-5) with what she was (2:6-4:1) and what God will make of her in the future (4:2-6). Thus the progress of thought is from the ideal to the real and back to the ideal.

 C. The analogy of wild grapes ch. 5

This is the third and last of Isaiah's introductory oracles. The first one (ch. 1) introduced the book as a whole by presenting major themes with which the prophet proceeded to deal in chapters 2-66. The second chiastic one (chs. 2-4) presented the tension between what God intended Israel to be and what she had become. This third prophetic sermon (ch. 5) was a clever presentation of the present condition of Israel in Isaiah's day and its consequences. It starts out deceptively as a casual song, transforms into a courtroom drama, and ends with pure condemnation. Isaiah lured his listeners into hearing him with a sweet song and then proceeded to burn them with fiery preaching.
