Judges 11:34-36

American Standard Version

³⁴ And Jephthah came to Mizpah unto his house; and, behold, his daughter came out to meet him with timbrels and with dances: and she was his only child; besides her he had neither son nor daughter. ³⁵ And it came to pass, when he saw her, that he rent his clothes, and said, Alas, my daughter! thou hast brought me very low, and thou art one of them that trouble me; for I have opened my mouth unto Jehovah, and I cannot go back. ³⁶ And she said unto him, My father, thou hast opened thy mouth unto Jehovah; do unto me according to that which hath proceeded out of thy mouth, forasmuch as Jehovah hath taken vengeance for thee on thine enemies, even on the children of Ammon.
