Judges 11:30-34

And Jephthah made a vow to the LORD. He said, “If you give me victory over the Ammonites, I will give to the LORD whatever comes out of my house to meet me when I return in triumph. I will sacrifice it as a burnt offering.” So Jephthah led his army against the Ammonites, and the LORD gave him victory. He crushed the Ammonites, devastating about twenty towns from Aroer to an area near Minnith and as far away as Abel-keramim. In this way Israel defeated the Ammonites. When Jephthah returned home to Mizpah, his daughter came out to meet him, playing on a tambourine and dancing for joy. She was his one and only child; he had no other sons or daughters.
