Bene-Jaakan. The full name is given in Deuteronomy 10:6 as Beeroth-beni-Jaakan, "the wells of the children of Jaakan." Jaakan, or Akan, was a grandson of Seir, the legendary tribe father of the Horites of Mount Seir (Genesis 36:20, Genesis 36:27; 1 Chronicles 1:42).
The wells of the Beni-Jaakan may well have retained their name long after their original owners had been dispossessed; or a remnant of the tribe may have held together until this time.
