Judges 11:29-35

Then the Spirit of Jehovah came upon Jephthah, and he passed over Gilead and Manasseh, and passed over Mizpeh of Gilead, and from Mizpeh of Gilead he passed over unto the children of Ammon. And Jephthah vowed a vow unto Jehovah, and said, If thou wilt indeed deliver the children of Ammon into my hand, then it shall be, that whatsoever cometh forth from the doors of my house to meet me, when I return in peace from the children of Ammon, it shall be Jehovah’s, and I will offer it up for a burnt-offering. So Jephthah passed over unto the children of Ammon to fight against them; and Jehovah delivered them into his hand. And he smote them from Aroer until thou come to Minnith, even twenty cities, and unto Abel-cheramim, with a very great slaughter. So the children of Ammon were subdued before the children of Israel. And Jephthah came to Mizpah unto his house; and, behold, his daughter came out to meet him with timbrels and with dances: and she was his only child; besides her he had neither son nor daughter. And it came to pass, when he saw her, that he rent his clothes, and said, Alas, my daughter! thou hast brought me very low, and thou art one of them that trouble me; for I have opened my mouth unto Jehovah, and I cannot go back.
