Judges 11:30-34

And Jephthah made a vow to the LORD, and said, “If You will indeed deliver the people of Ammon into my hands, then it will be that whatever comes out of the doors of my house to meet me, when I return in peace from the people of Ammon, shall surely be the LORD’s, and I will offer it up as a burnt offering.” So Jephthah advanced toward the people of Ammon to fight against them, and the LORD delivered them into his hands. And he defeated them from Aroer as far as Minnith—twenty cities—and to Abel Keramim, with a very great slaughter. Thus the people of Ammon were subdued before the children of Israel. When Jephthah came to his house at Mizpah, there was his daughter, coming out to meet him with timbrels and dancing; and she was his only child. Besides her he had neither son nor daughter.
