A river which flows from northern Samaria into the Mediterranean. Normally sluggish, it overflows during the rains and creates a surrounding area of swamp, which caused disaster to Sisera's chariots (Judg. 5: 21), as celebrated in Ps. 83: 9. It was also the scene of Elijah's massacre of the prophets of Baal after the contest on Mount Carmel (1 Kgs. 18: 40).
