Journal of Hebrew Scriptures - Volume 12 (2012) - Review
Isaiah After Exile, Jacob Stromberg's revised doctoral thesis, belongs in the growing corpus of studies that look at the text-historical development of the book of Isaiah. Stromberg explores the role of the author of the final layer of Isa 5666 (referred to by Stromberg as Trito-Isaiah [hereafter TI]) in shaping the book of Isaiah. Stromberg argues that this author, responsible for Isa 56:18; 6566, has shaped his own material in conscious continuity with and development of the existing Isaianic material in Isa 139* and 4055, as can be detected by numerous textual similarities and allusions. As such, he is an author of his own material, as well as a reader of the existing Isaianic material in Isa 155*. Moreover, he is a redactor insofar as he has added editorial comments at key places in the existing Isaianic material. Stromberg identifies the author of these editorial comments with TI because (1) the comments share the same theology as TI's writing in Isa 56; 6566* and (2) they develop the material in Isa 155* in the same way as does this writing.
In the brief introduction, Stromberg sets the stage for the following investigation and outlines his methodology. He points out that both reading and redacting are hermeneutical enterprises. We can expect the work of a redactor to reflect his reading of his sources, and we can expect his additions to earlier material to reflect his own writing.
Part I of the book focuses on the material in Isa 5666. Chapter one contains a detailed overview of the various theories pertaining to the formation of Isa 5666. Stromberg accepts the common view that the material in Isa 6062, as well as that in Isa 63:16 and Isa 63:764:11, forms the earliest parts of Isa 5666. In dialogue with previous scholarship, Stromberg also accepts the prevalent view that Isa 56:18 and 6566 constitute the latest material in Isa 5666 and form a framework around the earlier texts. He further argues that this later material presupposes and further develops the earlier texts. As to Isa 56:959:21, Stromberg tentatively agrees with P. A. Smith's view that it was written by the author of Isa 6566 but he chooses not to investigate that issue further.
Chapter 2 asks whether Isa 56:18; 6566 are original compositions or redactional assemblages of some sort. Expressed differently, is the unity of these texts on an authorial or a redactional level? Stromberg begins by looking at Isa 56:18 and argues, following especially G. Polan and P. A. Smith, that it is an authorial unity. Turning to Isa 65:166:17, he contends, against the views of especially Sekine and Koenen, that the structure of the material, its use of unique vocabulary, and its single purpose to serve as a response to the preceding lament (Isa 63:764:11), together suggest that it constitutes an authorial unity. Finally, Stromberg examines the textual relationship between Isa 56:18 and 66:1824, often understood as an editorial framework owing to the many parallels between the two texts. He demonstrates that, rather than distinguishing Isa 66:1824 from the preceding material in Isa 65:166:17, it is preferable to view all of Isa 56:18; 6566 as composed by the same author, Trito-Isaiah.
Part II looks at TI as the reader of the existing Isaianic material assumed to be at his disposal, i.e. Isa 139*; 4055; and 60:164:11. Which passages (intertexts) does TI allude to and what does he do with them? Stromberg does not suggest new intertexts but builds upon previous scholars' insights and aims to strengthen their arguments. The relatively short chapter 3 looks at the intertexts that TI used to shape the material in Isa 56:18. Stromberg argues, following primarily R. Rendtorff, that Isa 56:1 is a synthesis of the theme of צדקה and משפט in Isa 139 and the theme of צדקה and ישועה in Isa 4055. As such, Isa 56:1 declares that the call in Isa 139 to righteousness is still in force and should be understood as the basis for the enjoyment of God's promise of salvation as proclaimed in Isa 4055.
Stromberg then turns to the issue of the textual relationship between Isa 55 and 56 and concludes, in line especially with Beuken's research, that Isa 56:18 was written as a conscious development of Isa 55, a finding that explains the many similarities between the two passages. Again, this shows that TI regarded the existing material in Isa 4055 as still relevant to his own post-exilic audience, yet it was changed insofar as it now concerned (only) ethical individuals, including foreigners who wished to attach themselves to the God of Israel.
Stromberg also looks at the notion of the singular servant in Isa 4055 and the plural servants in Isa 56:18 and 6566. He argues that, as in the preceding case, TI moved away from the collective understanding of God's salvation in Isa 4055 and instead advocated a more narrow definition restricted to ethical individuals.
Stromberg finally demonstrates that Isa 56:8 alludes to Isa 11:12 rather than, as often argued, to Ps 147:2. His case is supported by, among other issues, Sweeney's claim that Isa 56:7 alludes to Isa 11:9. The fact that TI used Isa 11 as an intertext in 56:7 renders it likely that he used it again in an adjacent verse. Stromberg concludes that Isa 56:18 reinterprets the ingathering in Isa 11:12 to include also non-Israelites.
The substantial chapter 4 looks in a similar manner at the intertexts of Isa 6566. Through close studies of shared syntax, themes, and vocabulary, and building on previous scholars' insights, Stromberg argues convincingly that the author of Isa 6566 depended upon and reworked substantial amounts of material from Isa 139*; 4055; and 6062. Stromberg's analysis focuses on how TI read the earlier material as well as on the specific selection of texts that influenced him. According to Stromberg, TI sought in particular to redefine the identity of the recipients of God's salvation by excluding the wicked and sometimes including people from outside of Israel. Throughout the chapter, Stromberg discusses:
1. the use of 55:69 in 65:12;
2. the allusion to the former and latter things in 4048 in 65:16b18;
3. the allusion to 37:3 in 66:9, and the allusion to 37:30b in 65:21b;
4. the use of 11:69 in 65:25;
5. the echo of Isa 54:1, 11 in 66:714;
6. the reuse of 40:111 and 45:2025 in 66:1524 (40:5/66:1819; 40:10/66:15);
7. the allusions to 11:1116; 49:2223; and 62:1012 in 66:1824.
In Part III, Stromberg argues that TI redacted Isa 155*. At the time of TI's activity, a near final form of Isa 139* existed, with the likely exclusion of the so-called Isaiah apocalypse (Isa 2427). As to Isa 4055, Stromberg highlights that, regardless of whether we consider it as an authorial unity or as a gradually composed body of literature, it is likely that by the time of TI the material in Isa 4055 existed in its (near) final form.
Chapter 5 focuses on TI's redactional additions to select material in Isa 139. Stromberg limits his investigation to passages that many scholars recognize as editorial additions. Stromberg's decision is reasonable, given the limitations of a doctoral thesis, yet this selection means that other passages not discussed may also stem from TI's pen. In each instance, Stromberg begins by arguing that a verse is redactional. He then defines the manner in which the redactional verse refocuses the surrounding earlier material. If this manner is reminiscent of the manner in which TI, in his own writing in Isa 56:18 and 6566, refocused the material in Isa 155*, then Stromberg concludes that the redactor is TI. Stromberg argues that the following passages were composed by TI: Isa 1:2731; 6:13bβ; 4:26; 11:10; 7:15. He also suggests that TI was responsible for editing the material in Isa 3639.
As an example of Stromberg's argumentation, he notes that many scholars detect a strong affinity between Isa 6:13 and 65:9. He also notes that (other) scholars argue for the redactional origin of parts of this verse (v. 13bβ). He then evaluates and corroborates the claim that v. 13bβ is redactional, and shows how this quarter-verse refocuses the corporate tone of the surrounding material (where everyone will be destroyed) to a more individual tone (where the wicked will be destroyed but a righteous remnant will be saved). In the light of the observation that such a divisionbetween a wicked majority and a righteous minoritybrings to mind the theology evinced in Isa 56:18 and 6566, Stromberg concludes that TI is responsible for v. 13bβ.
The much shorter chapter 6 examines Isa 4055 in a similar manner. Stromberg investigates Isa 48:22 (nearly identical to Isa 57:21); 48:1 (sharing key vocabulary with Isa 59:1415); and 48:19b (reminiscent of Isa 66:22). Building upon previous scholarship, Stromberg confirms that (1) these three verses have a redactional character and (2) they introduce a distinction between the many wicked and the righteous few, not present in the surrounding verses. For example, the addition in Isa 48:22 functions as a conclusion to all of Isa 4048 and seeks to qualify the offer of salvation found in these chapters by excluding the wicked.
Finally, Stromberg looks at the many textual similarities between the material in Isa 54 and 5666. In particular, he shows that while Isa 54:17a contains a general offer of salvation, v. 17b, with its reference to the servants of the Lord, restricts the offer to a few righteous ones. This restriction of salvation is in line with the thinking found in Isa 66:714. A link between the two texts is further established by the affinity between Isa 54:11 and 66:13 and their shared use of the root נחם (comfort).
This is a very fine and well-researched monograph which can be highly recommended. The book is densely written, which means that it is not light reading, yet it is ultimately rewarding to be in the company of such a well-read and erudite author. Although many of the arguments in the book have been phrased before by different scholars in individual publications, Stromberg is the first to collect them, systematize them, and synthesize them into one coherent redactional theory.
One minor aspect open to critique is Stromberg's use of the term Trito-Isaiah. Most scholars have used that term to refer to either the author of Isa 6062*, understood to be the kernel of Isa 5666, or the material in Isa 5666 as a whole. Stromberg's use of the term as referring to the author of the final layer of texts in Isa 5666 is therefore difficult to get used to, and potentially confusing. The confusion is heightened by the fact that Stromberg also uses, for example in the title of his book, the phrase the author of Third Isaiah, which indicates that he takes the term TI to signify not only the author of the latest layer but also the layer itself.
