Judges 12:4-6

MLV(i) 4 Then Jephthah gathered together all the men of Gilead and fought with Ephraim. And the men of Gilead killed* Ephraim, because they said, You* are fugitives of Ephraim, you* Gileadites, in the midst of Ephraim, and in the midst of Manasseh.
5 And the Gileadites took the fords of the Jordan against the Ephraimites. And 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 they said to him, Say now Shibboleth and he said Sibboleth, for he could not frame to pronounce it right, then they laid hold on him and killed him at the fords of the Jordan. And there fell at that time of Ephraim forty-two thousand.
