29 Then the Spirit of the Lord came on Jephthah and he passed through Gilead and Manasseh, and passed through Mizpah of Gilead, and went on to the Ammonites.
30 Jephthah made a vow to the Lord, “If You will indeed give the Ammonites into my hands,
31 then whatever comes out from the door of my house to meet me, when I return safely from the Ammonites, will surely be the Lord’s, and I will offer it up as a burnt offering.”
32 So Jephthah crossed over to the Ammonites to wage war against them, and the Lord gave them into his hands.
33 He struck them down from Aroer to Minnith, twenty cities, and as far as Abel Keramim. The defeat was very severe, and the Ammonites were humbled before the children of Israel.
34 When Jephthah went to his house at Mizpah, there was his daughter coming out to meet him, dancing with a tambourine. She was his only child. Other than her, he had neither son nor daughter.
35 When he saw her, he ripped up his clothes and said, “Alas, my daughter! You have brought utter disaster to me. You are my undoing, for I have given my word to the Lord, and I cannot take it back.”
