35 And upon seeing her, he tore his garments, and he said: "Alas, my daughter! You have cheated me, and you yourself have been cheated. For I opened my mouth to the Lord, and I can do nothing else."
36 And she answered him, "My father, if you have opened your mouth to the Lord, do to me whatever you have promised, since victory has been granted to you, as well as vengeance against your enemies."
37 And she said to her father: "Grant to me this one thing, which I request. Permit me, that I may wander the hillsides for two months, and that I may mourn my virginity with my companions."
38 And he answered her, "Go." And he released her for two months. And when she had departed with her friends and companions, she wept over her virginity in the hillsides.
39 And when the two months expired, she returned to her father, and he did to her just as he had vowed, though she knew no man. From this, the custom grew up in Israel, and the practice has been preserved,
40 such that, after each year passes, the daughters of Israel convene as one, and they lament the daughter of Jephthah, the Gileadite, for four days.
