Genesis 36:38

Genesis 36 records the generations of Esau, who is Edom, listing his Canaanite and Ishmaelite wives and the sons and chiefs who descended from them. It traces the family lines of Eliphaz, Reuel, Jeush, Jalam, and Korah, and names the dukes who ruled the Edomite clans in their settlements. The chapter closes by affirming that these were the dukes of Edom, the nation descended from Esau, listed according to their territories and possessions.
