Judges 11:40

38 “Go,” he said. And he sent her away for two months. So she left with her friends and mourned her virginity upon the mountains.

39 After two months, she returned to her father, and he did to her as he had vowed. And she had never had relations with a man. So it has become a custom in Israel

that each year the young women of Israel go out for four days to lament the daughter of Jephthah the Gileadite.

Here the Bible tells a story about someone else. Ask yourself what it can say to us today. Do read the surrounding verses too, because the context often says more than a single verse.
