Dweller in the desert. (1.) One of the sons of Joktan, and founder of an Arabian tribe (Gen. 10:29). (2.) King of Edom, succeeded Bela (Gen. 36:33, 34). (3.) A Canaanitish king (Josh. 11:1) who joined the confederacy against Joshua.
Jobab
Jobab is a name that appears across several families, and the verses mostly list them. One Jobab is a son of Joktan in the family tree after the flood. Another, “the son of Zerah of Bozrah,” reigned over Edom after Bela died, in the list of kings who ruled before Israel had a king. Two more Jobabs are named among the sons of Benjamin in the Chronicles. Nothing is told of any of them beyond their place in the record, so there is no single story to follow. Genesis 36 shows the Edomite king in his setting, and the Genesis 10 list shows the earlier one.
