Judges 11:38-40

Holman Christian Standard Bible

³⁸ “Go,” he said. And he sent her away two months. So she left with her friends and mourned her virginity as she wandered through the mountains. ³⁹ At the end of two months, she returned to her father, and he kept the vow he had made about her. And she had never been intimate with a man. Now it became a custom in Israel ⁴⁰ that four days each year the young women of Israel would commemorate the daughter of Jephthah the Gileadite.
