Judges 11:30-35

30And Jephthah made a vow to the LORD : “If you give the Ammonites into my hands,

31whatever comes out of the door of my house to meet me when I return in triumph from the Ammonites will be the LORD ’s, and I will sacrifice it as a burnt offering.” 32Then Jephthah went over to fight the Ammonites, and the LORD gave them into his hands.

33He devastated twenty towns from Aroer to the vicinity of Minnith, as far as Abel Keramim. Thus Israel subdued Ammon. 34When Jephthah returned to his home in Mizpah, who should come out to meet him but his daughter, dancing to the sound of timbrels! She was an only child. Except for her he had neither son nor daughter.

35When he saw her, he tore his clothes and cried, “Oh no, my daughter! You have brought me down and I am devastated. I have made a vow to the LORD that I cannot break.”
