With Isaac's death, Moses proceeds to provide much detailed information regarding Esau's lineage in Genesis 36 before shifting the focus back to Jacob's family in chapter 37. Admittedly, most of this chapter is filled with names and appears to cover a number of generations. It is difficult to find much application for us today in this chapter full of names from thousands of years ago, so our comments here will be brief. "Now this is the genealogy of Esau, who is Edom" (36:1). Esau had married three women (two Canaanites as well as Ishmael's daughter) and was blessed with five sons and also some daughters. He became a grandfather many times over. "Then Esau took his wives, his sons, his daughters, and all the persons of his household, his cattle and all his animals, and all his goods which he had gained in the land of Canaan, and went to a country away from the presence of his brother Jacob. For their possessions were too great for them to dwell together, and the land where they were strangers could not support them because of their livestock. So Esau dwelt in Mount Seir. Esau is Edom" (Gen. 36:6-8). Jacob and Esau had the same problem as Abraham and Lot--extensive wealth prevented them from living near to one another. Esau chose to live in Mount Seir.
The rest of the chapter provides details concerning the chiefs of Edom, the sons of Seir, and even the kings who reigned in Edom long "before any king reigned over the children of Israel" (36:31).
