Hastings' Dictionary of the Bible 
JOBAB. 1. A son of Joktan in the genealogies ( Genesis 10:29 , 1 Chronicles 1:23 ), and therefore probably an Arabian geographical name. Glaser identifies Jobab with YHYBB (likely Yuhaybab ), a tribe mentioned in the SabÃ¦an inscriptions. Sprenger through the LXX [Note: Septuagint.] form Iobor relates it to WabÃ¢r , a considerable region in S. Arabia. 2. A king of Edom ( Genesis 36:33 f., 1 Chronicles 1:44 f.), confused, in the apocryphal appendix to the LXX [Note: Septuagint.] version of Job, with Job (see Job, Â§ 1). 3. A king of Madon, ally of Jabin of Hazor against Joshua ( Joshua 11:1 ). 4, 5. Name of two Benjamites ( 1 Chronicles 8:9; 1 Chronicles 8:18 ).

Fausset's Bible Dictionary 
1. Last of Joktan's sons ( Genesis 10:29; 1 Chronicles 1:23). Ptolemy mentions the Jobaritoe (perhaps Jobabitae ought to be read) among the Arabs.
2. King of Edom ( Genesis 36:33-34); son of Zerah of Bozrah; successor of Bela, first king. His association in kindred with Eliphaz (2) gives color to the conjecture that Jobab equates to Job.
3. Joshua 11:1.
4. 1 Chronicles 8:9.
Smith's Bible Dictionary

(Heb. Yobab', יוֹבָב , probably dweller in the Desert , from the Arabic; Sept. Ι᾿Ωβάβ , but in 1 Chronicles 1:23, Τὸν Εὐἱ Καὶ Τὸν ᾿Ωράμ , v.r. simply Ι᾿Ωάβ ), the name of several men.
1. The last-named of the sons of Joktan, and founder of a tribe in Arabia ( Genesis 10:29; 1 Chronicles 1:23), B.C. post 2414. Bochart compares ( Phaleg , 2, 29) the Jobaritoe ( Ιωβαρῖται ) of Ptolemy (6, 7, 24), a people on the eastern coast of Arabia, near the Socalitae, which, after Salmasius, he supposes to be for Jobabitoe; so also Michaelis (Spicileg. 2, 303; Supplem. 1013).
2. Son of Zerah of Bozrah, king of Edom after Bela and before Husham ( Genesis 36:33-34; 1 Chronicles 1:44-45), B.C. prob. long ante 1617. The supposition that he was identical with the patriarch Job rests only upon the apocryphal addition to the book of Job in the Sept., and is utterly unworthy of credit. (See Job).
3. The Canaanitish king of Madon, one of those whose aid Jabin invoked in the struggle with the Israelites ( Joshua 11:1), B.C. 1617.
4. The first-named of the sons of Shaharaim by one of his wives, Hodesh or Baara of the tribe of Benjamin, although apparently born in Moab ( 1 Chronicles 8:9), B.C. cir. 1612.
5. One of the "sons" of Elpaal, a chief of Benjamin, at Jerusalem ( 1 Chronicles 8:18), B.C. probably cir. 588.
