Genesis 35:26-29
35:26 The sons of Zilpah, Leah’s servant, were Gad and Asher.
These were the sons of Jacob who were born to him in Paddan Aram.
35:27 So Jacob came back to his father Isaac in Mamre, to Kiriath Arba (that is, Hebron), where Abraham and Isaac had stayed.
35:28 Isaac lived to be 180 years old.
35:29 Then Isaac breathed his last and joined his ancestors. He died an old man who had lived a full life. His sons Esau and Jacob buried him.
