JOBAB.—1. A son of Joktan in the genealogies (Gen_10:29, 1Ch_1:23), and therefore probably an Arabian geographical name. Glaser identifies Jobab with YHYBB (likely Yuhaybab), a tribe mentioned in the Sabæan inscriptions. Sprenger through the LXX [Note: Septuagint.] form Iobor relates it to Wabâr, a considerable region in S. Arabia. 2. A king of Edom (Gen_36:33 f., 1Ch_1:44 f.), confused, in the apocryphal appendix to the LXX [Note: Septuagint.] version of Job, with Job (see Job, § 1). 3. A king of Madon, ally of Jabin of Hazor against Joshua (Jos_11:1). 4, 5. Name of two Benjamites (1Ch_8:9; 1Ch_8:18).
