What does Genesis 35:29 mean?
Isaac dies at 180 years of age, "old and full of days." Something similar was said of his father Abraham when he died at 175 (Genesis 25:7). Isaac is buried in the family burial tomb at Mamre (Genesis 23:2–4; 35:27), by his twin sons Jacob and Esau (Genesis 25:23–28). This may be the first time Jacob and Esau have reunited since the resolution of their conflict when Jacob first re-entered the land of Canaan (Genesis 33:1–4). A similar reunion took place in the previous generation when Isaac and his half-brother Ishmael joined to bury Abraham in the same cave (Genesis 25:9).The death and burial of Isaac closes out this section of the book of Genesis. This portion is known as the "generations of Isaac" (Genesis 25:19). Previous sections were also named by the family patriarch involved (Genesis 6:9; 11:27). The following chapter will briefly explain the lineage of Esau (Genesis 36:1), much as an earlier passage did for Ishmael (Genesis 25:12), as they were not the ones to carry the line of God's chosen people. After this will come the final portion of Genesis, which explains the fate of Jacob's line (Genesis 37:2). A large part of this story will revolve around Jacob's favorite son (Genesis 37:3), Joseph (Genesis 30:22–24).
