Judges 11:34-36

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.” 36“My father,” she replied, “you have given your word to the LORD . Do to me just as you promised, now that the LORD has avenged you of your enemies, the Ammonites.
