Judges 11:30-34

Jephthah made a vow to the LORD and said, “If You will indeed give the Ammonites into my hand, then whatever comes out of the doors of my house to meet me when I return in peace from the Ammonites, it shall be the LORD’S, and I will offer it up as a burnt offering.” Then Jephthah crossed over to the Ammonites to fight with them; and the LORD gave them into his hand. And from Aroer to the entrance of Minnith he struck them, twenty cities, and as far as Abel-keramim (brook by the vineyard), with a very great defeat. So the Ammonites were subdued and humbled before the Israelites. Then Jephthah came to his house at Mizpah, and this is what he saw: his daughter coming out to meet him with tambourines and with dancing. And she was his only child; except for her he had no son or daughter.
