Judges 11:38-40

21st Century King James Version

³⁸ 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.

³⁹ 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. And it was a custom in Israel

⁴⁰ that the daughters of Israel went yearly to lament the daughter of Jephthah the Gileadite four days in a year.
