Judges 12:4-6

21st Century King James Version

⁴ Then Jephthah gathered together all the men of Gilead and fought with Ephraim; and the men of Gilead smote Ephraim, because they said, “Ye Gileadites are fugitives of Ephraim among the Ephraimites and among the Manassites.”

⁵ And the Gileadites seized the passages of the Jordan before the Ephraimites; and it was so, that when those Ephraimites who had escaped said, “Let me go over,” that the men of Gilead said unto him, “Art thou an Ephraimite?” If he said, “Nay,”

⁶ then said they unto him, “Say now Shibboleth.” And he said “Sibboleth,” for he could not frame to pronounce it right. Then they took him and slew him at the passages of the Jordan; and there fell at that time of the Ephraimites forty and two thousand.
