Judges 11:36-37

36And 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. 37And she said unto her father, Let this thing be done for me: let me alone two months, that I may depart and go down upon the mountains, and bewail my virginity, I and my companions.
