Genesis 35:22-24 International Standard Version (ISV)
22 But while Israel lived in that land, Reuben went inside his father’s tent[a] and had sexual relations with his father’s concubine Bilhah, and Israel heard about it. Now Jacob had twelve sons. 23 Leah’s sons were Reuben (Jacob’s first-born), Simeon, Levi, Judah, Issachar, and Zebulun. 24 Rachel’s sons were Joseph and Benjamin.
