Judges 11:29-39

29 And the spirit of the Lord came upon Jephthae, and he passed over Galaad, and Manasse, and passed by the watch-tower of Galaad to the other side of the children of Ammon.
30 And Jephthae vowed a vow to the Lord, and said, If thou wilt indeed deliver the children of Ammon into my hand,
31 then it shall come to pass that whosoever shall first come out of the door of my house to meet me when I return in peace from the children of Ammon, he shall be the Lord's: I will offer him up for a whole-burnt-offering.
32 And Jephthae advanced to meet the sons of Ammon to fight against them; and the Lord delivered them into his hand.
33 And he smote them from Aroer till comes to Arnon, in number twenty cities, and as far as Ebelcharmim, with a very great destruction: and the children of Ammon were straitened before the children of Israel.

35 And it came to pass when he saw her, that he rent his garments, and said, Ah, ah, my daughter, thou hast indeed troubled me, and thou wast the cause of my trouble; and I have opened my mouth against thee to the Lord, and I shall not be able to return from it.
36 And she said to him, Father, hast thou opened thy mouth to the Lord? Do to me accordingly as went out of thy mouth, in that the Lord has wrought vengeance for thee on thine enemies of the children of Ammon.
37 And she said to her father, Let my father now do this thing: let me alone for two months, and I will go up and down on the mountains, and I will bewail my virginity, I and my companions.
38 And he said, Go: and he sent her away for two months; and she went, and her companions, and she bewailed her virginity on the mountains.
39 And it came to pass at the end of the two months that she returned to her father; and he performed upon her his vow which he vowed; and she knew no man:

INTRODUCTION TO JUDGES 11

This chapter gives an account of another judge of Israel, Jephthah, of his descent and character, Jud 11:1-3 of the call the elders of Gilead gave him to be their captain general, and lead out their forces against the Ammonites, and the agreement he made with them, Jud 11:4-11 of the message he sent to the children of Ammon, which brought on a dispute between him and them about the land Israel possessed on that side Jordan the Ammonites claimed; Israel's right to which Jephthah defended, and made it clearly to appear, hoping thereby to put an end to the quarrel without shedding of blood, Jud 11:12-27 but the children of Ammon not attending to what he said, he prepared to give them battle, and previous to it he made a vow, and then set forward and fought them, and got the victory over them, Jud 11:28-33 and the chapter concludes with the difficulties Jephthah was embarrassed with upon his return home, on account of his vow, and the performance of it, Jud 11:34-40.
