Judges 11:33-38

³³and he smote from Aroer till that he came into Minnith, twenty cities, and unto Abel, which is set about with vineries or vines, with full great vengeance; and the sons of Ammon were made low of the sons of Israel.

³⁴And when Jephthah turned again into Mizpeh, his house, his one begotten daughter came to meet him with tympans, and crowds dancing; for he had not other free children.

³⁵And when he saw her, he rent his clothes, and said, Alas! my daughter, thou hast troubled me, and thou art troubled; for I opened my mouth to the Lord, and I may do none other thing.

³⁶To whom she answered, My father, if thou openedest thy mouth to the Lord, do to me whatever thing thou promisedest, while vengeance and victory of thine enemies be granted to thee.

³⁷And she said to her father, Give thou to me only this thing, which I beseech; suffer thou me that in two months I compass the hills, and bewail my maidenhood with my fellows.

³⁸To whom he answered, Go thou. And he suffered her in two months. And when she had gone forth with her fellows, and her play-frères, she bewept her maidenhood in the hills.
