37 Then she said to her father, “Let this thing be done for me: let me alone for two months, that I may go and wander on the mountains and bewail my virginity, my friends and I.”
38 So he said, “Go.” And he sent her away for two months; and she went with her friends, and bewailed her virginity on the mountains.
39 And it was so at the end of two months that she returned to her father, and he carried out his vow with her which he had vowed. She knew no man.And it became a custom in Israel
40 that the daughters of Israel went four days each year to lament the daughter of Jephthah the Gileadite.
