Genesis 35:26-30

and the sons of Zilpah, Leah’s female slave, were Gad and Asher. These were the sons of Jacob who were born to him in Paddan-aram.

Jacob came to his father Isaac at Mamre of Kiriath-arba (that is, Hebron), where Abraham and Isaac had resided.

Now the days of Isaac were 180 years.

Then Isaac breathed his last and died, and was gathered to his people, an old man of ripe age; and his sons Esau and Jacob buried him.
