Genesis 36:41-43

The Message

^40-43 And these are the chieftains from the line of Esau, clan by clan, region by region: Timna, Alvah, Jetheth, Oholibamah, Elah, Pinon, Kenaz, Teman, Mibzar, Magdiel, and Iram—the chieftains of Edom as they occupied their various regions.

This accounts for the family tree of Esau, ancestor of all Edomites.
