Judges 12:1–6

And the men of Ephraim were gathered together, and passed northward; and they said unto Jephthah, Wherefore passedst thou over to fight against the children of Ammon, and didst not call us to go with thee? we will burn thy house upon thee with fire. ²And Jephthah said unto them, I and my people were at great strife with the children of Ammon; and when I called you, ye saved me not out of their hand. ³And when I saw that ye saved me not, I put my life in my hand, and passed over against the children of Ammon, and Jehovah delivered them into my hand: wherefore then are ye come up unto me this day, to fight against me? ⁴Then Jephthah gathered together all the men of Gilead, and fought with Ephraim; and the men of Gilead smote Ephraim, because they said, Ye are fugitives of Ephraim, ye Gileadites, in the midst of Ephraim, and in the midst of Manasseh. ⁵And 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 unto him, Art thou an Ephraimite? If he said, Nay; ⁶then said they unto him, Say now Shibboleth; and he said Sibboleth; for he could not frame to pronounce it right: then they laid hold on him, and slew him at the fords of the Jordan. And there fell at that time of Ephraim forty and two thousand.
