Judges 12:1-3

1Then the men of Ephraim assembled and crossed the Jordan to Zaphon. They said to Jephthah, “Why have you crossed over to fight the Ammonites without calling us to go with you? We will burn your house down with you inside!”

2But Jephthah replied, “My people and I had a serious conflict with the Ammonites, and when I called, you did not save me out of their hands. 3When I saw that you would not save me, I risked my life and crossed over to the Ammonites, and the LORD delivered them into my hand. Why then have you come today to fight against me?”
