Judges 12:4-6

Amplified Bible, Classic Edition

⁴ Then Jephthah gathered all the men of Gilead and fought with Ephraim; and the men of Gilead smote Ephraim because they had said, You Gileadites are fugitives of Ephraim in the midst of Ephraim and Manasseh.

⁵ And the Gileadites took the fords of the Jordan before the Ephraimites; and when any of those Ephraimites who had escaped said, Let me go over, the men of Gilead said to him, Are you an Ephraimite? If he said, No,

⁶ They said to him, Then say Shibboleth; and he said, Sibboleth, for he could not pronounce it right. Then they seized him and slew him at the fords of the Jordan. And there fell at that time 42,000 of the Ephraimites.
