There are two major structural peculiarities that set Ezekiel off as distinctive.
First, the book is a collection of prophecies arranged in almost consistent chronological order. No other prophetical book is as consistently chronological as Ezekiel, except Habakkuk, and Zechariah comes close.16Furthermore, Ezekiel dated his oracles with unusual precision: usually by year, month, and day of the month.17He may have done this to stress the certainty of the predictions so that when they came to pass there would be no question as to their authenticity. A chart of the prophecies and their dates follows.
In the table above, the prophecies are in the order in which they appear in the text. For the most part, this is also the chronological order in which Ezekiel delivered them. However, you will note that the seventh and eighth groups of messages (beginning with 27:1 and 17) are not in chronological order. These messages are grouped topically with other prophecies against Egypt in chapters 29-32. Ezekiel's calendar, in the table, dates from the year of King Jehoiachin's (and Ezekiel's) exile (i.e., 598 B.C.; cf. 1:2). Scholars vary somewhat in their understanding of the modern equivalents of these dates. I have followed those of Dyer in The Bible Knowledge Commentary: Old Testament.
A second structural characteristic of the book is that it is logically organized as well as chronologically organized. First we read the call and preparation of the prophet (chs. 1-3). Then come prophecies announcing God's judgment on Judah culminating in the fall of Jerusalem (chs. 4-24). Next we find prophecies against foreign nations that opposed Israel (chs. 25-32). A section of prophecies on the coming restoration of Israel concludes the book (chs. 33-48).
"Apart from these obvious major divisions, this book is one of the easiest in the entire canon to outline, thanks to the clear demarcation of individual oracles. The book consists of fifty literary units, forty-eight of which are introduced either by a date notice or the word-event (also called prophetic word) formula, The word of Yahweh came to me saying.'"18
Ezekiel saw God's glory departing from the temple in judgment (9:3; 10:4, 18-19; 11:22-25), and then he saw it returning to the temple for blessing (43:1-5). These major events tie the book together. Ezekiel initially received a commission to deliver messages of judgment (chs. 2-3), but later he received another commission to deliver messages of deliverance (ch. 33). These two commissions identify the two major parts of the book that had particular relevance to Israel.
