Inilah para kepala kaum dari antara anak-anak Esau: anak-anak Elifas, anak sulung Esau, ialah kepala kaum Teman, kepala kaum Omar, kepala kaum Zefo, kepala kaum Kenas,
Rashi
אלה אלופי בני עשו THESE WERE CHIEFTAINS OF THE SONS OF ESAU — Heads of families.
Rashbam
All the Alufim mentioned in this chapter are heads of cities of clans. I believe that the אלוף קרח mentioned in this verse as one of the sons of Eliphaz is identical with the תמנע mentioned in Chronicles as a son of Eliphaz, (compare verse 12) whereas the קרח, mentioned in verse 18 here as the son of Oholovimah, is a different person by the same name.
Siftei Chakhamim
Heads of families. Rashi is saying they were leaders and heads, each over a different family, but not that the families were formed by them.
