²⁰ and Jacob set up a pillar at her grave; it is the pillar of Rachel’s tomb, which is there to this day. ²¹ Israel journeyed on, and pitched his tent beyond the tower of Eder.

²² While Israel lived in that land, Reuben went and lay with Bilhah his father’s concubine; and Israel heard of it.

Now the sons of Jacob were twelve.
