Judges 11:34-35

34Now when Jephthah arrived at his home in Mizpah, behold, his daughter was coming out to meet him with tambourines and with dances. Now she was his only child. Besides her he had no son or daughter.

35Upon seeing her, he tore his clothes and said, “Alas, my daughter! You made me bow down in grief—you’ve made me miserable! For I have opened my mouth to Adonai, and I cannot take it back.”
