She said to him, "My father, if you have opened your mouth to the Lord, do to me according to what has gone out of your mouth, now that the Lord has given you vengeance against your enemies, the Ammonites." And she said to her father, "Let this thing be done for me: Grant me two months, so that I may go and wander* on the mountains, and bewail my virginity, my companions and I." "Go," he said and sent her away for two months. So she departed, she and her companions, and bewailed her virginity on the mountains. At the end of two months, she returned to her father, who did with her according to the vow he had made. She had never slept with a man. (NRSV 11:36-39)
And she said unto him, My father, if thou hast opened thy mouth unto the LORD, do to me according to that which hath proceeded out of thy mouth; forasmuch as the LORD hath taken vengeance for thee of thine enemies, even of the children of Ammon. And she said unto her father, Let this thing be done for me: let me alone two months, that I may go up and down upon the mountains, and bewail my virginity, I and my fellows. And he said, Go. And he sent her away for two months: and she went with her companions, and bewailed her virginity upon the mountains. And it came to pass at the end of two months, that she returned unto her father, who did with her according to his vow which he had vowed: and she knew no man. (KJV 11:36-39)
Was Jephthah's sacrifice of his daughter really necessary? It wouldn't be the first time God required someone's death, of course, but this seems like such a fluke. Could this be saying something about the nature of violence and death?
