Genesis 35:29 DBY

²⁷  And Jacob came to Isaac his father to Mamre -- to Kirjath-Arba, which is Hebron; where Abraham had sojourned, and Isaac.

²⁸  And the days of Isaac were a hundred and eighty years.

²⁹  And Isaac expired and died, and was gathered to his peoples, old and full of days. And his sons Esau and Jacob buried him.
