Judges 7:24

The waters -The streams which run from the mountain district of Ephraim into the Jordan in the district of Beth-shan, forming great pools and marshes, which the Midianites fleeing south would have to cross before they could reach the Jordan fords. All the men of Ephraim -They had taken no previous part in the rising against Midian: nor had Gideon, of the smaller tribe of Manasseh, presumed before to summon his more powerful and arrogant brethren of the great tribe of Ephraim (seeJoshua 17:14-18).
