Genesis 36:23

And the children of Shobal were these; Alvan, and Manahath, and Ebal, Shepho, and Onam.

The naming of Shobal's sons belongs to the record devoted wholly to Esau and to the nations that came from him. Its historical place falls ten or eleven years after Jacob rejoiced under God's blessing at Peniel. At that time Jacob was about one hundred nine years old, Joseph was seventeen, and Benjamin was a small child two to four years old.
