A city on the borders of Edom in the Negev. It was given to the tribe of Judah (Joshua 15:30). In another lists of towns, Chesil is replaced by:
Bethul (Joshua 19:4)
Bethuel (1 Chronicles 4:30)
Perhaps Bethel, though not the Bethel north of Jerusalem (1 Samel 30:27)
Bethuel or Bethul is considered by many scholars to be the original name, with Chesil as a later error.
See also Bethuel, Bethul (Place).
