Judges 12:1-4

1And the men of Ephraim were called together, and passed over northwards, 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.

2And Jephthah said to them, I was at great strife, I and my people, with the children of Ammon; and I called you, but ye saved me not out of their hand.

3And when I saw that ye would not save me, I put my life in my hand, and passed over against the children of Ammon, and Jehovah gave them into my hand. Why then are ye come up to me this day, to fight against me?

4And Jephthah gathered together all the men of Gilead, and fought with Ephraim; and the men of Gilead smote Ephraim, because they said, Ye, Gilead, ye are fugitives of Ephraim in the midst of Ephraim, [and] in the midst of Manasseh.
