Judges 11:35-36
11:35 When he saw her, he ripped his clothes and said, “Oh no! My daughter! You have completely ruined me! You have brought me disaster! I made an oath to the Lord, and I cannot break it.”
11:36 She said to him, “My father, since you made an oath to the Lord, do to me as you promised. After all, the Lord vindicated you before your enemies, the Ammonites.”
