Genesis 35:22-29

22While Israel lived in that land, Reuben went and lay with Bilhah his father's concubine. And Israel heard of it. Now the sons of Jacob were twelve.

23The sons of Leah: Reuben (Jacob's firstborn), Simeon, Levi, Judah, Issachar, and Zebulun.

24The sons of Rachel: Joseph and Benjamin.

25The sons of Bilhah, Rachel's servant: Dan and Naphtali.

26The sons of Zilpah, Leah's servant: Gad and Asher. These were the sons of Jacob who were born to him in Paddan-aram.

27And Jacob came to his father Isaac at Mamre, or Kiriath-arba (that is, Hebron), where Abraham and Isaac had sojourned.

28Now the days of Isaac were 180 years.

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