Genesis 36:5

And Aholibamah bare Jeush, and Jaalam, and Korah,.... In this genealogy mention is made of another Korah among the sons of Eliphaz,

Genesis 36:16; which Jarchi thinks is the same with this, and takes him to be a bastard, and begotten in incest by Eliphaz, on his father's wife Aholibamah; but Aben Ezra observes, that some are of opinion that there were two Korahs, one the son of Aholibamah, and the other the son of Adah; but he thinks there were but one, which was the son of Aholibamah, and is reckoned among the sons of Eliphaz, because he dwelt among them; or perhaps his mother died when he was little, and Adah brought him up with her sons, and so was reckoned her son; such were the children of Michal, Saul's daughter:

these [are] the sons of Esau, which were born to him in the land of Canaan; and we do not read of any born to him elsewhere; so that of all his wives, which some think were four, others five, he had but five sons; what daughters he had is not related, though from Genesis 36:6, it appears he had some.
