Judges 12:2-3

2And Jephthah said to them, “My people and I were in a great struggle with the people of Ammon; and when I called you, you did not deliver me out of their hands.

3So when I saw that you would not deliver me, I took my life in my hands and crossed over against the people of Ammon; and the Lord delivered them into my hand. Why then have you come up to me this day to fight against me?”
