Thematic Bible: Defeated by him

Then Jephthah mustered all the men of Gilead, fought the tribe of Ephraim, and defeated them, because they had been claiming, "You descendants of Gilead are fugitives in the midst of the tribes of Ephraim and Manasseh." The descendants of Gilead seized control of the Jordan River's fords along the border of Ephraim's territory. Later on, when any fugitive from Ephraim asked them, "Let me cross over," the men from Gilead would ask him, "Are you an Ephraimite?" If he said "No," they would order him, "Pronounce the word "Shibboleth' right now." If he said "Sibboleth," not being able to pronounce it correctly, they would seize him and slaughter him there at the fords of the Jordan River. During those days 42,000 descendants of Ephraim died that way.
