Judges 12:5-7

King James Version

⁵ And the Gileadites took the passages of Jordan before the Ephraimites: and it was so, that when those Ephraimites which were 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 Jordan: and there fell at that time of the Ephraimites forty and two thousand.

⁷ And Jephthah judged Israel six years. Then died Jephthah the Gileadite, and was buried in one of the cities of Gilead.
