Genesis 35:25

22 And it came to pass, when Israel dwelt in that land, that Reuben went and lay with Bilhah his father's concubine: and Israel heard it. Now the sons of Jacob were twelve:

23 The sons of Leah; Reuben, Jacob's firstborn, 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, which were born to him in Padanaram.

27 And Jacob came unto Isaac his father unto Mamre, unto the city of Arbah, which is Hebron, where Abraham and Isaac sojourned.

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