One of the waterways near the Jordan River. When Gideon was at war with Midian, he anticipated that they would flee to this place and asked the tribe of Ephraim to guard it.
Judges 7:24Gideon sent messengers throughout the hill country of Ephraim, saying, “Come down against Midian and seize the waters ahead of them as far as Beth-barah and the Jordan.” So all the men of Ephraim gathered and seized the waters as far as Beth-barah and the Jordan.
