Judges 12:1-3

Now the men of Ephraim were summoned, and they crossed to Zaphon; and they said to Jephthah, “Why did you cross over to fight against the sons of Ammon without calling us to go with you? We will burn your house down on you!”

So Jephthah said to them, “I and my people were in a major dispute with the sons of Ammon; and I did call you, but you did not save me from their hand.

When I saw that you were no deliverer, I took my life in my hands and crossed over against the sons of Ammon, and the Lord handed them over to me. Why then have you come up to me this day to fight against me?”
