37. And she said to her father, “Let this thing be done for me: grant me two months so that I may go wander on the mountains and lament over my virginity, I and my companions.
38. And he said, “Go.” He sent her away for two months, and she went with her friends, and she lamented over her virginity on the mountains.
39. At the end of the two months she returned to her father, and he did to her according to his vow; and she did not sleep with a man. And it became an annual custom in Israel
40. for the daughters of Israel to go and lament the daughter of Jephthah the Gileadite for forty days of the year.
