Genesis 35:28

26The sons of Zilpah (Leah’s servant): Gad and Asher. These are the sons of Jacob, who were born to him in Paddan Aram.

27Jacob came to Isaac his father, to Mamre, to Kiriath Arba (which is Hebron), where Abraham and Isaac lived as foreigners.

28The days of Isaac were one hundred eighty years.

29Isaac gave up the spirit and died, and was gathered to his people, old and full of days. Esau and Jacob, his sons, buried him.
