Genesis 35:22-29

22And it happened, when Israel dwelt in that land, that Reuben went and lay with Bilhah his father’s concubine; and Israel heard about it. Now the sons of Jacob were twelve:

23the sons of Leah were Reuben, Jacob’s firstborn, and Simeon, Levi, Judah, Issachar, and Zebulun;

24the sons of Rachel were Joseph and Benjamin;

25the sons of Bilhah, Rachel’s maidservant, were Dan and Naphtali;

26and the sons of Zilpah, Leah’s maidservant, were Gad and Asher. These were the sons of Jacob who were born to him in Padan Aram.

27Then Jacob came to his father Isaac at Mamre, or Kirjath Arba (that is, Hebron), where Abraham and Isaac had dwelt.

28Now the days of Isaac were one hundred and eighty years.

29So Isaac breathed his last and died, and was gathered to his people, being old and full of days. And his sons Esau and Jacob buried him.
