Judges 12:1-3

Then the people of Ephraim mobilized an army and crossed over the Jordan River to Zaphon. They sent this message to Jephthah: “Why didn’t you call for us to help you fight against the Ammonites? We are going to burn down your house with you in it!” Jephthah replied, “I summoned you at the beginning of the dispute, but you refused to come! You failed to help us in our struggle against Ammon. So when I realized you weren’t coming, I risked my life and went to battle without you, and the LORD gave me victory over the Ammonites. So why have you now come to fight me?”
