Jephthah said, “Go and do that.” Jephthah sent her away for two months. Jephthah’s daughter and her friends stayed in the mountains. They cried for her because she would not marry and have children.
Then Jephthah’s daughter said to her father, “But do this one thing for me first. Let me be alone for two months. Let me go to the mountains. I will not marry and have children, so let me and my friends go and cry together.”
At the end of two months, Jephthah’s daughter returned to her father. Jephthah did what he promised to the Lord. Jephthah’s daughter never had sexual relations with anyone. So this became a custom in Israel.
