9 These then are the records of the generations of Esau the father of the Edomites in the hill country of Seir. 10These are the names of Esau’s sons: Eliphaz the son of Esau’s wife Adah, Reuel the son of Esau’s wife Basemath. 11 The sons of Eliphaz were Teman, Omar, Zepho and Gatam and Kenaz. 12 Timna was a concubine of Esau’s son Eliphaz and she bore Amalek to Eliphaz. These are the sons of Esau’s wife Adah. 13 These are the sons of Reuel: Nahath and Zerah, Shammah and Mizzah. These were the sons of Esau’s wife Basemath. 14These were the sons of Esau’s wife Oholibamah, the daughter of Anah and the granddaughter of Zibeon: she bore to Esau, Jeush and Jalam and Korah.
15 These are the chiefs of the sons of Esau. The sons of Eliphaz, the firstborn of Esau, are chief Teman, chief Omar, chief Zepho, chief Kenaz, 16 chief Korah, chief Gatam, chief Amalek. These are the chiefs descended from Eliphaz in the land of Edom; these are the sons of Adah. 17 These are the sons of Reuel, Esau’s son: chief Nahath, chief Zerah, chief Shammah, chief Mizzah. These are the chiefs descended from Reuel in the land of Edom; these are the sons of Esau’s wife Basemath. 18 These are the sons of Esau’s wife Oholibamah: chief Jeush, chief Jalam, chief Korah. These are the chiefs descended from Esau’s wife Oholibamah, the daughter of Anah. 19 These are the sons of Esau (that is, Edom), and these are their chiefs.
It’s interesting that one of the descendants of Esau was Amalek, possibly the father of the Amalekites. Even though Esau and Jacob had mended their relationship as best they could, and Esau had moved to the hill country to avoid conflict, it would not be avoided forever, and Amalek would be right in the middle of that conflict. It would never be resolved until after the Israelites had been taken into captivity, and Esther foiled the plot of Haman the Agagite, a descendant of Amalek. There was continually bad blood between the two brothers because of Jacob’s treachery against Esau. If you hold a grudge, it can go far beyond yourself. It can carry on for generations if people let it. Don’t.
