Genesis 25:8-10
25:8 Then Abraham breathed his last and died at a good old age, an old man who had lived a full life. He joined his ancestors.
25:9 His sons Isaac and Ishmael buried him in the cave of Machpelah near Mamre, in the field of Ephron the son of Zohar, the Hethite.
25:10 This was the field Abraham had purchased from the sons of Heth. There Abraham was buried with his wife Sarah.
