Genesis 35:22-26

22While Israel lived in that land, Reuben went and alay with Bilhah his father’s concubine. And Israel heard of it.

Now the sons of Jacob were twelve.
23The sons of Leah: bReuben (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.
