JDG 7:24

24 He also sent messengers throughout the hilly area where the descendants of Ephraim lived, saying, “Come down to attack the army of Midian. Come down to the Jordan River, to the place where people can wade across, to prevent enemy troops from crossing it! Station men as far south as Beth-Barah.” So the men of Ephraim did what Gideon told them to do.
