Judges 12:6 WEB

⁴  Then Jephthah gathered together all the men of Gilead, and fought with Ephraim; and the men of Gilead struck Ephraim, because they said, You are fugitives of Ephraim, you Gileadites, in the midst of Ephraim, [and] in the midst of Manasseh.

⁵  The Gileadites took the fords of the Jordan against the Ephraimites. It was so, that when [any of] the fugitives of Ephraim said, Let me go over, the men of Gilead said to him, Are you an Ephraimite? If he said, No;

⁶  then said they to him, Say now Shibboleth; and he said Sibboleth; for he couldn't manage to pronounce it right: then they laid hold on him, and killed him at the fords of the Jordan. There fell at that time of Ephraim forty-two thousand.

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

⁸  After him Ibzan of Bethlehem judged Israel.
