Is Job the same man as Jobab, king of Edom?

Type: interpretive argument (off-timeline) · Assessment: weak — the identification of Job of Uz with Jobab son of Zerah of Bozrah, the second king of Edom (Genesis 36:33), does not hold as a claim about a single historical man. It is asserted only by the Septuagint appendix (Job 42:17b–e), a paragraph absent from the Hebrew that flags itself as reporting “the Syriac book” — a tradition, not the text — and it rests on two thin supports: a resemblance between the names Job and Jobab that all but vanishes in Hebrew (’Iyyob vs. Yobab, different roots; the likeness is largely an artefact of the Greek Iōb/Iōbab), and the shared Edomite setting. Against it stand the Hebrew’s silence (Job is never a king, never linked to Edom’s monarchy; the suffering hero and the bare name in a king-list have nothing in common but a similar name), and the appendix’s own visible seams — it turns Bozrah, Jobab’s city, into “his mother Bosorrha,” and buys its “fifth from Abraam” by collapsing a generation out of the Esau genealogy. What the tradition honestly attests is a real and early belief — that Job was an Edomite Gentile of the patriarchal age — which converges with (without by itself establishing) the south-Edom lean of where Uz lay and the patriarchal-age lean of when Job lived. The bare person-identification, though, is a harmonising conjecture built on the name, not a datum.

The question

The Hebrew book of Job gives its hero a name and a homeland but no genealogy, no era, and no royal office: “There was a man in the land of Uz, whose name was Job” (Job 1:1). The Greek translators filled all of that in at a stroke. Where the Hebrew closes at Job’s death, the Old Greek adds a paragraph — conventionally Job 42:17a–e — that names his former name as Jobab, sets his home “on the borders of Idumea and Arabia,” runs his line back through Esau to Abraham, and slots him into the Edomite king-list of Genesis 36:31–35 as Bela’s successor: “after Balac, Jobab, who is called Job.” In the Hebrew that second king is “Jobab the son of Zerah of Bozrah” (Genesis 36:33). The question weighed here is narrow and testable: is Job of Uz that man — the same historical person as the Edomite king Jobab — or is the equation a later harmonisation? (Where Uz lay and when Job lived are weighed on their own pages; this one asks only whether the two names denote one man.)¹

The identification, and its pedigree (steelman)

The case for the identification is not negligible, and it should be put at its strongest before it is weighed.

An old and independent tradition, not a stray gloss. The equation is not the whim of a single copyist. It is already told, before the Greek Job was made, by the Hellenistic-Jewish writer Aristeas the Exegete, whose Concerning the Jews — excerpted by Alexander Polyhistor and preserved by Eusebius — says that Esau “begat Job,” who dwelt in Uz “on the borders of Idumaea and Arabia” and “was at first called Jobab.” The appendix and Aristeas track each other so closely that the Greek supplement is judged to draw on the same Second-Temple tradition, pushing the Job = Jobab equation back at least to the third–second century BC. It was then carried forward: the first-century Testament of Job has Job say outright, “before the Lord had named me Job, I was called Jobab… I am of the sons of Esau,” and the Edomite-king reading was assumed by a long line of later readers. This is a coherent, early, and widely-received identification, not a late invention.²

The name. In Greek the two names are nearly the same word — Iōb and Iōbab — so that “Jobab, who is called Job” reads almost as a shortening of the one into the other. To a reader of the Septuagint the identification looks less like a claim than an observation.³

It fits the setting the other cues point to. An Edomite king of Bozrah, a great-grandson of Esau “fifth from Abraam,” is exactly a man of the patriarchal age and of Edomite country — the very milieu that Job’s more-than-two-century lifespan and pre-Levitical sacrifice suggest for his era, and that Lamentations’ “daughter of Edom… in the land of Uz” and “Eliphaz the Temanite” suggest for his place. The identification does not merely assert a name; it supplies, in one move, a who, a when, and a where that all cohere with the book’s own atmosphere. That coherence is its real strength.⁴

The defeaters (folded in): a secondary text, a Hebrew name that does not match, and visible seams

Each of those supports gives way under pressure, and no positive counter-thesis is needed to see why — the identification simply fails to carry its own weight.

It stands on a secondary text that reports a tradition. The paragraph is absent from the Hebrew, from the Peshitta, from the Qumran Job Targum (11QtgJob), and from the Rabbinic Targum; it survives only as an addition to the Greek. And it does not claim to be the book: it pauses to name its source — “this man is described in the Syriac book” — a citation formula found nowhere else in the Greek Job. The appendix thus tells the reader itself that it is transmitting an outside tradition about Job, not a datum from the book of Job. Whatever weight the identification has is the weight of that tradition, and no more.⁵

The names do not match in Hebrew. The Greek likeness is misleading. In Hebrew the hero is ’Iyyob (אִיּוֹב, root ’-y-b) and the Edomite king is Yobab (יוֹבָב, root y-b-b) — two different names from two different roots, sharing only an opening syllable and a soft b. The near identity that makes the equation feel natural is an accident of Greek transcription, which flattens both toward Iōb(ab). Once that mirage is removed, the onomastic hook — the single most persuasive-looking prop — is gone, and the resemblance looks less like evidence for the identification than like the very thing that generated it.⁶

Nothing in the Hebrew ties the sufferer to Edom’s throne. The two figures have nothing in common but the similar name. The Job of the Hebrew book is never called a king and is never connected to the Edomite monarchy; the Jobab of Genesis 36:33 is a bare entry in a royal succession — a name, a father, a city, no story, no suffering, no righteousness, no wager, no restoration. The whole substance of who Job is — the trial, the friends, the whirlwind — is simply absent from the king-list, and the whole substance of Jobab — that he reigned in Edom — is absent from the book of Job. Two records that share only a look-alike name, and disagree on everything a name is attached to, are weak grounds for one man.⁷

The appendix’s own genealogy has seams. The compilation shows its stitching in two places. First, it turns a place-name into a parent: Genesis makes Jobab a man “of Bozrah” — his city — but the Greek reads “his mother Bosorrha,” a plain misreading of the Hebrew. Second, its “fifth from Abraam” is purchased by shortening the line: it calls Zerah “one of the sons of Esau,” whereas Genesis makes Zerah Esau’s grandson, son of Reuel (Genesis 36:13) — so the count “Abraham, Isaac, Esau, Zerah, Jobab” works only by dropping Reuel out. And behind both lies a deeper strain: the Hebrew king-list itself does not present the Edomite kings as a single Esau dynasty — they “reigned in the land of Edom, before there reigned any king over the children of Israel” (Genesis 36:31), each from a different city, reading more like an elective succession than a descent, so that grafting Jobab onto Esau’s line is the appendix’s inference, not the text’s. A genealogy that misreads a city as a mother and telescopes a generation to hit a round number is an interpretive construction, not an archive.⁸

Adversarial assessment

What the identification genuinely attests. Stripped of its overclaim, the tradition is a real datum of reception: by the third–second century BC, Jewish readers already placed Job as an Edomite Gentile of the patriarchal age, descended from Esau, living on the Edom–Arabia frontier. That belief is old, coherent, and independently transmitted (Aristeas, the appendix, the Testament of Job), and it points the same way as the book’s own cues about Job’s milieu. As evidence for where Job was imagined to belong and when the story is set, it is a genuine early witness, and it is used as such on the Uz and era pages — as convergent corroboration, never as the load-bearing proof.

Why that does not yield the identification. None of this establishes that Job is the particular Jobab of the king-list. The whole edifice rests on the name; remove the Greek coincidence and the Hebrew names are simply different, the two figures share no attribute but a similar sound, the supporting text is a secondary addition that flags itself as hearsay, and the genealogy that would seat Job on Edom’s throne is demonstrably stitched (Bozrah → mother; a dropped generation; a king-list that is not a dynasty). The likeliest account is the reverse of the claim: the name-similarity did not reveal that Job was Jobab, it produced the identification — a natural harmonising move that gave the placeless hero a slot in the one Edomite register Scripture supplied. This is why critical study, and the honest reading of the appendix’s own seams (noted since Schürer), treats the equation as an early conjecture rather than a preserved fact.

How it bears on the other two Job cruxes. The three questions the tradition raised — where Job lived, when he lived, and whether he was Jobab — interlock, and the temptation is to let the identification settle all three at once (an Edomite king of Bozrah in the patriarchal age answers place, era, and genealogy together). But an argument cannot be strengthened by leaning on the weakest member of its own set. Because the identification fails, the place-question and the era-question must stand on their own evidence — and they do: Uz resolves toward Edom from Lamentations 4:21 and Eliphaz the Temanite without Jobab, and the patriarchal milieu follows from the lifespan and the pre-Levitical sacrifice without Jobab. The identification is thus the weakest of the three cruxes, and the other two are deliberately kept independent of it so that its collapse does not take them down.

Assessment

Weak. On its best available case the identification of Job with Jobab king of Edom does not hold as a claim about one historical man. Its supports are two, and both give way: the Greek near-homonymy Iōb/Iōbab dissolves in Hebrew, where ’Iyyob and Yobab are different names from different roots; and the only text that asserts the equation is the Septuagint appendix, a paragraph absent from the Hebrew (and from the Peshitta and the Job Targums) that names its own source as “the Syriac book” — a tradition reported, not a datum of the book — and that carries demonstrable seams, misreading Jobab’s city Bozrah as “his mother” and reaching “fifth from Abraam” only by dropping Reuel out of the Esau line (Genesis 36:13). Against the equation, the Hebrew never makes Job a king or links him to Edom’s monarchy, and the Jobab of the king-list is a bare name with no story of suffering; the two share nothing but a look-alike name, which is far likelier to have generated the identification than to attest it. What is not weak, and is conceded in full, is the tradition’s real content: an early, coherent, independently-transmitted belief (Aristeas, the appendix, the Testament of Job) that Job was an Edomite Gentile of the patriarchal age. That belief converges with — but does not by itself establish — the south-Edom lean of where Uz lay and the patriarchal-age lean of when Job lived, both of which resolve on their own scriptural evidence and are kept independent of this identification precisely because it cannot bear their weight. Distinct throughout, as on the other Job pages, is the book’s own date and authorship (a literary question) from the placing of the man. The full text of the appendix, the Aristeas parallel, and the scholarship are on the Septuagint-appendix detail page; the witnesses are gathered on the Job timeline.
