Genesis 35:27-29

27 Jacob came to his father Isaac at Mamre, or Kiriath-arba (that is, Hebron), where Abraham and Isaac had resided as aliens.
28 Now the days of Isaac were one hundred eighty years.
29 And Isaac breathed his last; he died and was gathered to his people, old and full of days; and his sons Esau and Jacob buried him.
