Judges 11:29-33

At that time the Spirit of the LORD came upon Jephthah, and he went throughout the land of Gilead and Manasseh, including Mizpah in Gilead, and from there he led an army against the Ammonites. 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.
