22While Israel was living in that region, Reuben went in and slept with his father’s concubine Bilhah, and Israel heard about it. Jacob had twelve sons:
23The sons of Leah were Reuben the firstborn of Jacob, Simeon, Levi, Judah, Issachar, and Zebulun.
24The sons of Rachel were Joseph and Benjamin.
25The sons of Rachel’s maidservant Bilhah were Dan and Naphtali.
26And the sons of Leah’s maidservant Zilpah were Gad and Asher. These are the sons of Jacob, who were born to him in Paddan-aram.
