Genesis 35:22-26 - The Sons Of Jacob
22 It happened, while Israel lived in that land, that Reuben went and lay with Bilhah, his father's concubine, and Israel heard of it. Now the sons of Jacob were twelve. 23 The sons of Leah: Reuben (Jacob's firstborn), Simeon, Levi, Judah, Issachar, and Zebulun. 24 The sons of Rachel: Joseph and Benjamin. 25 The sons of Bilhah (Rachel's handmaid): Dan and Naphtali. 26 The sons of Zilpah (Leah's handmaid): Gad and Asher. These are the sons of Jacob, who were born to him in Paddan Aram.
