Genesis 35:25

22 And it came to pass, while Israel dwelt 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 first-born, and Simeon, and Levi, and Judah, and Issachar, and Zebulun;

24 the sons of Rachel: Joseph and Benjamin;

25 and the sons of Bilhah, Rachel`s handmaid: Dan and Naphtali;

26 and the sons of Zilpah, Leah`s handmaid: Gad and Asher: these are the sons of Jacob, that were born to him in Paddan-aram.

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

28 And the days of Isaac were a hundred and fourscore years.
