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.
Now look, notice, Jephthah was a very egocentric person. Notice all the I's and the my's and so forth in these next few verses. It demonstrates the guy's egocentricities.
