Duke Korah: As it is certain from Genesis 36:4, that Eliphaz was Esau's son by Adah, and from Genesis 36:11 and Genesis 36:12, that Eliphaz had but six sons, "Teman, Omar, Zepho, Gatam, Kenaz, and Amalek;" as is is also certain, from Genesis 36:5 and Genesis 36:14, that Korah was the son of Esau (not Eliphaz) by Aholibamah; and as the words duke Korah are omitted by both the Samaritan text and version, Dr. Kennicott pronounces them to be an interpolation.
