Judges 11:34-35

34After that, Jephthah returned to his home in Mizpah. As he arrived, his daughter came out to meet him. She was dancing and making music with a tambourine. She was Jephthah's only child. He had no other son or daughter.

35When Jephthah saw her, he was so upset that he tore his clothes. He said, ‘Oh no! My daughter! You have made me very sad. I made a serious promise to the Lord and I must do what I promised.’
