Judges 12:4-6 Modern English Version (MEV)
4 Then Jephthah assembled all the men of Gilead and fought with Ephraim. The men of Gilead struck Ephraim down, for they had said, “You Gileadites are fugitives in Ephraim, living in Ephraim and Manasseh.” 5 Gilead captured the fords of the Jordan River leading to Ephraim. Whenever an Ephraimite fugitive would say, “Let me cross,” the Gileadite men would say to him, “Are you an Ephraimite?” If he said, “No,” 6 then they would say to him, “Say, ‘Shibboleth’!” Yet he would say, “Sibboleth,” for he could not pronounce it correctly. Then they would grab him and kill him at the Jordan fords. During that time forty-two thousand from Ephraim fell.
