Genesis 35:22-27

22While Israel was living in that region, Reuben went in and slept with his father’s concubine Bilhah, and Israel heard of it. Jacob had twelve sons:

23The sons of Leah: Reuben the firstborn of Jacob, Simeon, Levi, Judah, Issachar and Zebulun.

24The sons of Rachel: Joseph and Benjamin.

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

26The sons of Leah’s servant Zilpah: Gad and Asher. These were the sons of Jacob, who were born to him in Paddan Aram. 27Jacob came home to his father Isaac in Mamre, near Kiriath Arba (that is, Hebron), where Abraham and Isaac had stayed.
