Judges 12:1-7 - Tribal Conflict Between Gilead And Ephraim
1 And the men of Ephraim assembled, and went northward, and said to Jephthah, Why didst thou pass 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.
2 And Jephthah said to them, I and my people were at great strife with the children of Ammon; and when I called you, ye delivered me not out of their hands. 3 And when I saw that ye delivered me not, I put my life in my hands, and passed over against the children of Ammon, and the LORD delivered them into my hand: why then have ye come up to me this day, to fight against me?
4 Then Jephthah collected all the men of Gilead, and fought with Ephraim: and the men of Gilead smote Ephraim, because they said, Ye Gileadites are fugitives of Ephraim among the Ephraimites, and among the Manassites. 5 And the Gileadites took the passages of Jordan before the Ephraimites: and it was so, that when those Ephraimites who had escaped, said, Let me go over; that the men of Gilead said to him, Art thou an Ephraimite? If he said, No; 6 Then said they to 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.
