Genesis 35:24

21 Israel journeyed, and spread his tent beyond the tower of Eder.

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.

27 Jacob came to Isaac his father, to Mamre, to Kiriath-arba (the same is Hebron), where Abraham and Isaac sojourned.
