Judges 12:3-6

BSB(i) 3 When I saw that you would not save me, I risked my life and crossed over to the Ammonites, and the LORD delivered them into my hand. Why then have you come today to fight against me?” 4 Jephthah then gathered all the men of Gilead and fought against Ephraim. And the men of Gilead struck them down because the Ephraimites had said, “You Gileadites are fugitives in Ephraim, living in the territories of Ephraim and Manasseh.” 5 The Gileadites captured the fords of the Jordan leading to Ephraim, and whenever a fugitive from Ephraim would say, “Let me cross over,” the Gileadites would ask him, “Are you an Ephraimite?” If he answered, “No,” 6 they told him, “Please say Shibboleth.” If he said, “Sibboleth,” because he could not pronounce it correctly, they seized him and killed him at the fords of the Jordan. So at that time 42,000 Ephraimites were killed.
