Genesis 35:27-29

Jacob came to Isaac his father at Mamre of Kiriath-arba (that is, Hebron), where Abraham and Isaac had lived temporarily. Now the days of Isaac were a hundred and eighty years. Isaac’s spirit departed and he died and was gathered to his people [who had preceded him in death], an old man full of days (satisfied, fulfilled); his sons Esau and Jacob buried him [in the cave of Machpelah with his parents Abraham and Sarah].
