What Happened to Yiftach's Daughter?

(30) And Jephthah made the following vow to GOD: “If You deliver the Ammonites into my hands, (31) then whatever comes out of the door of my house to meet me on my safe return from the Ammonites shall be GOD’s and shall be offered by me as a burnt offering.” (32) Jephthah crossed over to the Ammonites and attacked them, and GOD delivered them into his hands. (33) He utterly routed them—from Aroer as far as Minnith, twenty towns—all the way to Abel-cheramim. So the Ammonites submitted to the Israelites. (34) When Jephthah arrived at his home in Mizpah, there was his daughter coming out to meet him, with hand-drum and dance! She was an only child; he had no other son or daughter. (35) On seeing her, he rent his clothes and said, “Alas, daughter! You have brought me low; you have become my troubler! For I have uttered a vow to GOD and I cannot retract.” (36) “Father,” she said, “you have uttered a vow to GOD; do to me as you have vowed, seeing that GOD has vindicated you against your enemies, the Ammonites.” (37) She further said to her father, “Let this be done for me: let me be for two months, and I will go with my companions and lament upon the hills and there bewail my maidenhood.” (38) “Go,” he replied. He let her go for two months, and she and her companions went and bewailed her maidenhood upon the hills. (39) After two months’ time, she returned to her father, and he did to her as he had vowed. She had never known a man. So it became a custom in Israel (40) for the maidens of Israel to go every year, for four days in the year, and chant dirges for the daughter of Jephthah the Gileadite.

Another interpretation (of Lev. 27:2) “When anyone explicitly vows […]”: This text is related (to Prov. 11:30), “The fruit of the righteous is a tree of life, but a wise person acquires lives (npshwt).” If a person is righteous, and does not occupy himself with Torah, even though he is righteous, he has nothing in his possession. Rather, “The fruit of the righteous is a tree of life”; this refers to the Torah. Because when one is a Torah scholar (literally, child of Torah), he learns how one acquires lives (npshwt), as stated (ibid.), “but a wise person acquires lives.” As if he makes a vow for the value of human beings, he would have learned what to do from the Torah. But if he does not have Torah in his possession, he has nothing in his possession. And so you find in the case of Jephthah the Gileadite, because he was not a Torah scholar, he lost his daughter. When? In the time that he fought with the Children of Ammon and made a vow at that time, as stated (in Jud. 11:30-31), “Then Jephthah made a vow to the Lord, [and said, ‘If You indeed give the Children of Ammon into my hand;] Then it shall be that whatever comes forth…, shall belong to the Lord, and I will offer it up as a burnt offering.’” At that time the Holy One, blessed be He, was angry with him. The Holy One, blessed be He, said, “If there had come out from his house a dog, a pig, or a camel, he would have offered it to Me.” Hence He summoned his daughter to him. And why so much? So that all those that vow will learn the laws of vows and abnegations. [And the result was (in Jud. 11:34-35),] “and there was his daughter coming out to greet him [….] And it came to pass, when he saw her, that he rent his clothes […].” But was not Phinehas there? And still he said (in vs. 35), “and I cannot retract?” However, Phinehas had said, “I am a high priest and the son of a high priest. Shall I humble myself and go to an ignoramus ('am ha'arets)?” [And] Jephthah said, “I am head of the tribes of Israel and head of the magistrates. Shall I humble myself and go to a commoner?” Between the two of them that poor woman perished from the world; so the two of them were liable for her blood. In the case of Phinehas, the holy spirit left him. In the case of Jephthah, his bones were scattered, as stated (in Jud. 12:7), “and he was buried in the cities of Gilead.” When he sought to sacrifice her, she cried in front of him. His daughter said to him, “My father, I came out to greet you in joy, and [now] you slaughter me? Is it perhaps that the Holy One, blessed be He, wrote in the Torah that Israel offer the lives (npshwt) of people in front of the Holy One, blessed be He? And is it not written (in Lev. 1:2), ‘When one of you presents an offering to the Lord from the beasts.’ ‘From the beasts’ and not from people?” He said to her, “My daughter, I made a vow (in Jud. 11:31), ‘Then it shall be that whatever comes forth […].’ Is it possible that anyone who makes a vow does not have to fulfill his vow?” She said to him, “Behold, when our father Jacob made a vow (in Gen. 28:22), ‘and of all that You give me, I will surely set aside a tithe for You’; when the Holy One, blessed be He, gave him twelve sons, did he ever offer up one of them as a sacrifice? Moreover, does not Hannah [do likewise], when she makes a vow and says (as reported in I Sam. 1:11), ‘And she made a vow and said, “Lord of hosts, if You will surely see… [then I will give him to the Lord all the days of his life].”’ Did she ever offer up her son as a sacrifice to the Holy One, blessed be He?” All these things she said to him, but he did not heed her. When she saw that he did not heed her, she said to him, “Let me go to a court of law. Perhaps one of them will find a loophole for your words.” Thus it is stated (in Jud. 11:37), “leave me alone for two months, so that I may go and come down to the mountains.” R. Zechariah said, “Is there anyone who comes down to the mountains? Does not one go up to the mountains? So what is the meaning of ‘and come down to the mountains?’ These represent the Sanhedrin, as in the usage (of Micah 6:2), ‘Hear, O mountains, the lawsuit of the Lord.’” She went to them, but they did not find a loophole for undoing his vow, because of the sin of those that he slaughtered from the tribe of Ephraim. So it is with reference to him that Scripture has said (in Prov. 28:3), “A poor man who exploits the indigent is a torrential rain which leaves no bread.” “A poor man who exploits the indigent.” This is referring to Jephthah; since he was poor in Torah like a [mere] sycamore shoot. (Prov. 28:3, cont.:) “Who exploits the indigent,” since he exploited the indigent, when he said [to the men of Ephraim] (in Jud. 12:6), “Say, ‘Shibboleth’; and he said, ‘Sibboleth,’ not being able to pronounce it correctly.” Then he slaughtered him. Therefore, he is (according to Prov. 28:3, cont.) “a torrential rain, and there is no bread,” in that he had someone who would undo his vow; however (ibid., cont.), “there is no bread,” in that the Holy One, blessed be He, had taken away the halakhah from them, so that they would not find [a loophole] for undoing his vow. When they did not find [a loophole] for undoing his vow, he went up and slaughtered her before the Holy One, blessed be He. Then the holy spirit proclaimed, “Did I desire you to sacrifice lives (npshwt) to Me, [lives] (according to Jer. 19:5), ‘which I never commanded, never spoke for, and which never entered My mind.’” “Which I never commanded” Abraham, that he slaughter his son. Instead I said to him (in Gen. 22:12), “Do not raise your hand against the lad.” [This was] in order to make known Abraham’s love [of God] to the nations of the world, that he did not spare his only one from Me and carried out the will of his Maker. (Jer 19:5 cont.:) “Never spoke” to Jephthah to offer up his daughter as a sacrifice to Me. Rabbi Johanan and R. Simeon ben Laqish [differed on the matter]. Rabbi Johanan says, “He was liable for money [in order to fulfill his vow], like the matter is written in Arakhin.” And R. Simoen ben Laquish said, “[He was liable for] nothing, as he made a stipulation about something that is impossible to sacrifice, and [so] there was no [liability] upon him.” “And which never entered my mind,” this is referring to Misha the king of Moab, about whom it is written that when he fell into the hand of the king of Israel (in II Kings 3:27), “And he took his firstborn son, who would become king in his stead, and offered him up as a burnt offering upon the wall.” What caused Misha to sacrifice his son? Because he was not a Torah scholar; for if he had read the Torah, he would not have lost his son, since it is written (in Lev 27:2-4) “When anyone explicitly vows [to the Lord the value of human beings (npshwt)] And the value of a male shall be […]. And if it is a female….” Ergo (in Prov. 11:30), “but a wise person acquires lives (npshwt).”

She became the subject of a law. Legislation was enacted prohibiting any repetition of this, for, had he approached Pinchos, or had Pinchos approached him, he would have released him from his vow. But they refused to humble themselves, and were, thus, both responsible for her ruin. They were punished. The Divine Presence departed from Pinchos, as it is said in Divrei Hayamim, "Adonoy was with him previously." We learn that he was not with him later. And Yiftoch was afflicted with ulcerations and the loss of his limbs, as it is said, "He was buried in the cities of Gilod." Another interpretation: "She became the subject of a law in Yisroel" relates to the following passage.

And he did to her [as he had vowed]. She separated from human company to live alone, busy with the worship of God. And our teachers of blessed memory have said (Ta'anit 4a) that he vowed to sacrifice as a burnt offering all that came out of his house, and so he performed his vow.
