Ramban
AND THESE ARE THE GENERATIONS OF ESAU THE FATHER OF EDOM. Scripture comes to mention the generations which his children begot after they went with him to Se’ir for Esau did not beget there. Thus Scripture begins from him by saying that he had already begotten Eliphaz and Re’uel,259Verse 10 here. and they begot these children in the land of Se’ir. It also mentions together with them the children of Oholibamah,260Verse 14 here. who were born in the land of Canaan,261Verse 5 here. even though it does not mention any children that were born to them in the land of Se’ir,262According to Ramban above, the justification for mentioning the birth of Eliphaz and Re’uel was in order to mention their offspring. Why then was the birth of Oholibamah’s children mentioned? The answer is: “in order that they, etc.” so that they be counted together with their brothers, the sons of Esau, mentioned in the beginning of the section. It is also mentioned because they became chieftains in Se’ir since Scripture mentions all their chieftains.
