Jephthah answered, "I and my people were engaged in a great struggle with the Ammonites, and although I called, you didn't save me out of their hands.
When I saw that you wouldn't help, I took my life in my hands4 and crossed over to fight the Ammonites, and the LORD gave me the victory5 over them. Now why have you come up today to fight me?"
