Judges 11:29-40 - Jephthah Makes A Vow
29 Then the Spirit of Jehovah came on Jephthah, and he passed over Gilead and Manasseh, and passed over Mizpeh of Gilead, and from Mizpeh of Gilead passed over to the sons of Ammon. 30 And Jephthah vowed a vow to Jehovah, and said, If You will indeed give the sons of Ammon into my hand, 31 then it shall be that whatever comes out from the doors of my house to meet me when I return in peace from the sons of Ammon, surely it shall belong to Jehovah, or I will offer it up instead of a burnt offering.
32 And Jephthah passed over to the sons of Ammon to fight against them. And Jehovah delivered them into his hand. 33 And he struck them from Aroer even until you come to Minnith, twenty cities, and to the meadow of the vineyards, with a very great slaughter. So were the sons of Ammon subdued before the sons of Israel.
34 And Jephthah came to Mizpeh to his house, and, behold, his daughter came out to meet him with timbrels and with dances. And she was his only child. Besides her he had neither son nor daughter. 35 And it happened when he saw her, he tore his clothes and said, Alas, my daughter! You have brought me very low, and you are one of those who trouble me. For I have opened my mouth to Jehovah, and I cannot go back.
36 And she said to him, My father, you have opened your mouth to the Lord; do to me according to that which has come out of your mouth, because Jehovah has taken vengeance for you upon your enemies, even of the sons of Ammon. 37 And she said to her father, Let this thing be done for me. Let me alone two months, so that I may go up and down upon the mountains and weep for my virginity, I and my companions.
38 And he said, Go. And he sent her away for two months. And she went with her companions and wept for her virginity upon the mountains. 39 And it happened at the end of two months she returned to her father, who did to her his vow which he had vowed. And she knew no man. And it is a custom in Israel, 40 that the daughters of Israel went yearly to tell again of the daughter of Jephthah the Gileadite, four days in a year.
