²¹ Isra’el continued his travels and pitched his tent on the other side of Migdal-‘Eder. ²² It was while Isra’el was living in that land that Re’uven went and slept with Bilhah his father’s concubine, and Isra’el heard about it.

Ya‘akov had twelve sons. ²³ The sons of Le’ah were Re’uven Ya‘akov’s firstborn, Shim‘on, Levi, Y’hudah, Yissakhar and Z’vulun.
