Genesis 35:22-26 - The Sons Of Jacob
22 And it came to pass while Israel inhabited that land, that Reuben went and lay with Bilhah his father's concubine; and Israel heard of it. And so the Sons of Israel came to be Twelve. 23 The sons of Leah, the firstborn of Jacob, Reuben, - And Simeon and Levi and Judah, and Issachar and Zebulon: 24 The sons of Rachel, Joseph and Benjamin: 25 And the sons of Bilhah, handmaid of Rachel, Dan, and Naphtali: 26 And the sons of Zilpah, handmaid of Leah, Gad and Asher: These, are the sons of Jacob, who were born to him, in Padan-aram.
