What does Genesis 36:40 mean?
This final section of the chapter lists the chiefs of Esau in the region of Edom (Genesis 36:1). This list differs both from the list of the sons of Esau (Genesis 36:9–14) and of the kings of Edom (Genesis 36:31–39). It's possible these names came to represent specific clans and geographical regions of Edom.The chiefs of Esau included Timna, Alvah, and Jetheth.
