Carchemish
(fortress of Chemosh) occupied nearly the site of the later Mabug or Hierapolis. It seems to have commanded the ordinary passage of the Euphrates at Bir or Birekjik . Carchemish appears to have been taken by Pharoah Necho shortly after the battle of Megiddo (cir. B.C. 608), and retaken by Nebuchadnezzar after a battle three years later, B.C. 605. (Jeremiah 46:2)
