1 Now Jephthah the Gileadite was a mighty man of valour, and he was the son of an harlot: and Gilead begat Jephthah. 2 And Gilead's wife bare him sons; and his wife's sons grew up, and they thrust out Jephthah, and said unto him, Thou shalt not inherit in our father's house; for thou art the son of a strange woman. 3 Then Jephthah fled from his brethren, and dwelt in the land of Tob: and there were gathered vain men to Jephthah, and went out with him. 4 And it came to pass in process of time, that the children of Ammon made war against Israel. 5 And it was so, that when the children of Ammon made war against Israel, the elders of Gilead went to fetch Jephthah out of the land of Tob: 6 And they said unto Jephthah, Come, and be our captain, that we may fight with the children of Ammon. 7 And Jephthah said unto the elders of Gilead, Did not ye hate me, and expel me out of my father's house? and why are ye come unto me now when ye are in distress? 8 And the elders of Gilead said unto Jephthah, Therefore we turn again to thee now, that thou mayest go with us, and fight against the children of Ammon, and be our head over all the inhabitants of Gilead. 9 And Jephthah said unto the elders of Gilead, If ye bring me home again to fight against the children of Ammon, and the LORD deliver them before me, shall I be your head? 10 And the elders of Gilead said unto Jephthah, The LORD be witness between us, if we do not so according to thy words. 11 Then Jephthah went with the elders of Gilead, and the people made him head and captain over them: and Jephthah uttered all his words before the LORD in Mizpeh. 12 And Jephthah sent messengers unto the king of the children of Ammon, saying, What hast thou to do with me, that thou art come against me to fight in my land? 13 And the king of the children of Ammon answered unto the messengers of Jephthah, Because Israel took away my land, when they came up out of Egypt, from Arnon even unto Jabbok, and unto Jordan: now therefore restore those lands again peaceably. 14 And Jephthah sent messengers again unto the king of the children of Ammon: 15 And said unto him, Thus saith Jephthah, Israel took not away the land of Moab, nor the land of the children of Ammon: 16 But when Israel came up from Egypt, and walked through the wilderness unto the Red sea, and came to Kadesh; 17 Then Israel sent messengers unto the king of Edom, saying, Let me, I pray thee, pass through thy land: but the king of Edom would not hearken thereto. And in like manner they sent unto the king of Moab: but he would not consent: and Israel abode in Kadesh. 18 Then they went along through the wilderness, and compassed the land of Edom, and the land of Moab, and came by the east side of the land of Moab, and pitched on the other side of Arnon, but came not within the border of Moab: for Arnon was the border of Moab. 19 And Israel sent messengers unto Sihon king of the Amorites, the king of Heshbon; and Israel said unto him, Let us pass, we pray thee, through thy land into my place. 20 But Sihon trusted not Israel to pass through his coast: but Sihon gathered all his people together, and pitched in Jahaz, and fought against Israel. 21 And the LORD God of Israel delivered Sihon and all his people into the hand of Israel, and they smote them: so Israel possessed all the land of the Amorites, the inhabitants of that country. 22 And they possessed all the coasts of the Amorites, from Arnon even unto Jabbok, and from the wilderness even unto Jordan. 23 So now the LORD God of Israel hath dispossessed the Amorites from before his people Israel, and shouldest thou possess it? 24 Wilt not thou possess that which Chemosh thy god giveth thee to possess? So whomsoever the LORD our God shall drive out from before us, them will we possess. 25 And now art thou any thing better than Balak the son of Zippor, king of Moab? did he ever strive against Israel, or did he ever fight against them, 26 While Israel dwelt in Heshbon and her towns, and in Aroer and her towns, and in all the cities that be along by the coasts of Arnon, three hundred years? why therefore did ye not recover them within that time? 27 Wherefore I have not sinned against thee, but thou doest me wrong to war against me: the LORD the Judge be judge this day between the children of Israel and the children of Ammon. 28 Howbeit the king of the children of Ammon hearkened not unto the words of Jephthah which he sent him. 29 Then the Spirit of the LORD came upon Jephthah, and he passed over Gilead, and Manasseh, and passed over Mizpeh of Gilead, and from Mizpeh of Gilead he passed over unto the children of Ammon. 30 And Jephthah vowed a vow unto the LORD, and said, If thou shalt without fail deliver the children of Ammon into mine hands, 31 Then it shall be, that whatsoever cometh forth of the doors of my house to meet me, when I return in peace from the children of Ammon, shall surely be the LORD's, and I will offer it up for a burnt offering. 32 So Jephthah passed over unto the children of Ammon to fight against them; and the LORD delivered them into his hands. 33 And he smote them from Aroer, even till thou come to Minnith, even twenty cities, and unto the plain of the vineyards, with a very great slaughter. Thus the children of Ammon were subdued before the children of Israel. 34 And Jephthah came to Mizpeh unto his house, and, behold, his daughter came out to meet him with timbrels and with dances: and she was his only child; beside her he had neither son nor daughter. 35 And it came to pass, when he saw her, that he rent his clothes, and said, Alas, my daughter! thou hast brought me very low, and thou art one of them that trouble me: for I have opened my mouth unto the LORD, and I cannot go back. 36 And she said unto him, My father, if thou hast opened thy mouth unto the LORD, do to me according to that which hath proceeded out of thy mouth; forasmuch as the LORD hath taken vengeance for thee of thine enemies, even of the children of Ammon. 37 And she said unto her father, Let this thing be done for me: let me alone two months, that I may go up and down upon the mountains, and bewail my virginity, I and my fellows. 38 And he said, Go. And he sent her away for two months: and she went with her companions, and bewailed her virginity upon the mountains. 39 And it came to pass at the end of two months, that she returned unto her father, who did with her according to his vow which he had vowed: and she knew no man. And it was a custom in Israel, 40 That the daughters of Israel went yearly to lament the daughter of Jephthah the Gileadite four days in a year.
[AD 1781] Richard Challoner on Judges 11:24
Chamos: The idol of the Moabites and Ammonites. He argues from their opinion, who thought they had a just title to the countries which they imagined they had conquered by the help of their gods: how much more then had Israel in indisputable title to the countries which God, by visible miracles, had conquered for them.
[AD 373] Ephrem the Syrian on Judges 11:30-31
People imitate those who do good deeds, therefore, not out of love for these good deeds but because of their utility.… The king of Moab took note of Jephthah. But, because it was his firstborn and a human being rather than an animal that he killed, God took pity on him, since he did it in affliction and not through love. In the case of Jephthah, if it had been one of his servants who had been first to encounter him, he would have killed him. But, in order that people would not engage in the sacrifice of their fellow human beings, he caused his own daughter to meet him, so that others would be afraid, lest they offer human beings by vow to God.

[AD 420] Jerome on Judges 11:30-31
And whereas he [Jovinianus] prefers the fidelity of the father Jephthah to the tears of the virgin daughter, that corroborates our point. For we are not commending virgins of the world so much as those who are virgins for Christ’s sake. Most Hebrews blame the father for the rash vow he made, “If you will indeed deliver the children of Ammon into my hand, then it shall be that whatsoever comes out of the doors of my house to meet me, when I return in peace from the children of Ammon, it shall be for the Lord’s, and I will offer it up for a burnt offering.” Supposing (the Hebrews say) a dog or an ass had met him, what would he have done? Their meaning is that God so ordered events that he who had improvidently made a vow should learn his error by the death of his daughter.

[AD 430] Augustine of Hippo on Judges 11:30-31
With these words [of his vow] at any rate Jephthah did not vow some kind of animal that he could offer as a whole burnt offering according to the law; it is neither customary now nor was it in the past that cattle would run to meet generals returning victoriously from war. As far as mute animals are concerned, dogs often run to meet their masters and sport with them in fawning servitude. But Jephthah could not have been thinking about dogs in his vow, because it would seem that he would have vowed not only something unlawful but also something contemptible and unclean according to the law. It would have been an insult to God. Nor does he say, “I will offer as a whole burnt offering whatever will come out of the doors of my house to meet me.” He says, “I will sacrifice whoever comes out of my house.” Thus, there can be no doubt that he was thinking of nothing else than a human being—not his only daughter, however. Yet who would have been able to surpass her in her father’s eyes except perhaps his wife?

[AD 1781] Richard Challoner on Judges 11:31
Whosoever: Some are of opinion, that the meaning of this vow of Jephte, was to consecrate to God whatsoever should first meet him, according to the condition of the thing; so as to offer it up as a holocaust, if it were such a thing as might be offered by the law; or to devote it otherwise to God, if it were not such as the law allowed to be offered in sacrifice. And therefore they think the daughter of Jephte was not slain by her father, but only consecrated to perpetual virginity. But the common opinion followed by the generality of the holy fathers and divines is, that she was offered as a holocaust, in consequence of her father's vow: and that Jephte did not sin, at least not mortally, neither in making, nor in keeping, his vow: since he is no ways blamed for it in scripture; and was even inspired by God himself to make the vow (as appears from ver. 29, 30) in consequence of which he obtained the victory; and therefore he reasonably concluded that God, who is the master of life and death, was pleased on this occasion to dispense with his own law; and that it was the divine will he should fulfil his vow.
[AD 253] Origen of Alexandria on Judges 11:34-38
The remaining sacrifices, of which those relating to the law are a symbol, are akin to this sacrifice. But in addition, the other sacrifices akin to this sacrifice seem to me to be the shedding of the blood of the noble martyrs. It was not in vain that the disciple John saw them standing beside the heavenly altar. “But who is wise, that he shall understand these things? Or intelligent, and he shall know them?”3Now comprehend, even if to a limited extent, the more spiritual sense of such sacrifices which cleanse those for whom they are offered; one must understand the sense of the sacrifice of the daughter of Jephthah who was offered as a burnt offering because of the vow of him who conquered the children of Ammon. She who was offered as a burnt offering consented to this vow, for, when her father said, “I have opened my mouth to the Lord against you,” she said to him, “And if you have opened your mouth to the Lord against me, perform your vow.”
Such accounts give an appearance of great cruelty to God to whom such sacrifices are offered for humanity’s salvation. We need a generous and perceptive spirit in order to refute the reproaches made against providence and, at the same time, to make a defense of all the sacrifices insofar as they are rather mysterious and beyond human nature.

[AD 430] Augustine of Hippo on Judges 11:34-38
The Scriptures do not seem to pass judgment on this vow and its fulfillment as it does quite clearly in the case of Abraham, when he was ordered to sacrifice his son and did so. Rather the Scriptures seem to have only recorded the matter and left it to the reader to evaluate, just as in the case of Judah, Jacob’s son, who in ignorance lay with his daughter-in-law but committed fornication by the very act, because he thought her to be a prostitute. The Scriptures never approve nor disapprove of the act explicitly but let the matter stand, to be evaluated and contemplated after consulting the righteousness and law of God. Therefore, the Scriptures of God do not offer any comment in either the vow or its fulfillment, so that our mind might be put to work to pass judgment on this matter and so that we might now say that such a vow displeased God and led to the punishment that his only daughter, of all people, ran out to meet her father.

[AD 1781] Richard Challoner on Judges 11:37
Bewail my virginity: The bearing of children was much coveted under the Old Testament, when women might hope that from some child of theirs, the Saviour of the world might one day spring. But under the New Testament virginity is preferred. 1 Cor. 7. 35.
[AD 397] Ambrose of Milan on Judges 11:39-40
It is also sometimes contrary to duty to fulfill a promise or to keep an oath. As was the case with Herod, who swore that whatever was asked he would give to the daughter of Herodias, and so allowed the death of John, that he might not break his word. And what shall I say of Jephthah, who offered up his daughter in sacrifice, she having been the first to meet him as he returned home victorious; whereby he fulfilled the vow which he had made that he would offer to God whatever should meet him first. It would have been better to make no promise at all than to fulfill it in the death of his daughter.

[AD 397] Ambrose of Milan on Judges 11:39-40
Never shall I be led to believe that the leader Jephthah made his vow otherwise than without thought, when he promised to offer to God whatever should meet him at the threshold of his house on his return. For he repented of his vow, as afterwards his daughter came to meet him. He tore his clothes and said, “Alas, my daughter, you have entangled me, you have become a source of trouble for me.” And though with pious fear and reverence he took upon himself the bitter fulfillment of his cruel task, yet he ordered and left to be observed an annual period of grief and mourning for future times. It was a hard vow, but far more bitter was its fulfillment, while he who carried it out had the greatest cause to mourn. Thus it became a rule and a law in Israel from year to year, as it says: “that the daughters of Israel went to lament the daughter of Jephthah the Gileadite four days in a year.” I cannot blame the man for holding it necessary to fulfill his vow, but yet it was a wretched necessity which could only be solved by the death of his child.…What, then, in the case of esteemed and learned people is full of marvel, that in the case of a virgin is found to be far more splendid, far more glorious, as she says to her sorrowing father, “Do to me according to that which has proceeded out of your mouth.” But she asked for a delay of two months in order that she might go about with her companions upon the mountains to bewail fitly and dutifully her virginity now given up to death. The weeping of her companions did not move her, their grief did not prevail upon her, nor did their lamentations hold her back. She did not allow the day to pass, nor did the hour escape her notice. She returned to her father as though returning according to her own desire, and of her own will [she] urged him on when he was hesitating, and acted thus of her own free choice, so that what was at first an awful chance became a pious sacrifice.

[AD 407] John Chrysostom on Judges 11:39-40
For Jephthah likewise, when he had promised that the first thing that met him, after a victorious battle, he would sacrifice, fell into the snare of child murder; for his daughter first meeting him, he sacrificed her, and God did not forbid it. And I know, indeed, that many of the unbelievers impugn us of cruelty and inhumanity on account of this sacrifice; but I should say that the concession in the case of this sacrifice was a striking example of providence and clemency; and that it was in care for our race that he did not prevent that sacrifice. For if after that vow and promise he had forbidden the sacrifice, many also who were subsequent to Jephthah, in the expectation that God would not receive their vows, would have increased the number of such vows, and proceeding on their way would have fallen into child murder. But now, by suffering this vow to be actually fulfilled, he put a stop to all such cases in the future. And to show that this is true, after Jephthah’s daughter had been slain, in order that the calamity might be always remembered and that her fate might not be consigned to oblivion, it became a law among the Jews that the virgins assembling at the same season should bewail during forty days the sacrifice which had taken place; in order that renewing the memory of it by lamentation, they should make all people wiser for the future; and that they might learn that it was not after the mind of God that this should be done, for in that case he would not have permitted the virgins to bewail and lament her. And that what I have said is not conjectural, the event demonstrated; for after this sacrifice, no one vowed such a vow to God. Therefore also he did not indeed forbid this; but what he had expressly commanded in the case of Isaac, that he directly prohibited, plainly showing through both cases that he does not delight in such sacrifices.

[AD 430] Augustine of Hippo on Judges 11:39-40
As regards to the fact that Jephthah sacrificed his daughter to God as a whole burnt offering, these are the facts: he had vowed that if he were to obtain the victory, he would offer as a whole burnt offering whoever would come out of his house and meet him; because he had vowed this and won the battle and his daughter had been the one to meet him first, he fulfilled his vow. This event has become a great and rather difficult question to settle both for some who investigate the matter with piety and genuinely seek to know what this passage means and for some who out of ignorant impiety oppose the Holy Scriptures and call this a horrible misdeed that the God of the law and prophets would have delighted in sacrifices, yes, even human sacrifices. First let us reply to their calumnies by noting that the whole burnt offerings of cattle did not delight the God of the law and the prophets—or as I prefer to say, the God of Abraham, Isaac and Jacob. What pleased God about those sacrifices was that they were full of meaning and a foreshadowing of future things. We, however, have the very substance which was foreshadowed by these sacrifices that he wished to commend to us. Moreover, there was also a very pertinent reason why those sacrifices have been changed so that they no longer are commanded but even forbidden: it is so that we may not think that God is pleased by such sacrifices according to some carnal passion.

[AD 430] Augustine of Hippo on Judges 11:39-40
But we rightly ask whether human sacrifices must have foreshadowed future events.… But if this were true, this type of sacrifice would not displease God. But in fact the Scriptures themselves clearly testify that human sacrifices displease him. For when God wanted and commanded all the firstborn to belong to him and to be his, he nonetheless wanted the firstborn of humankind to be redeemed by their parents, so that they would not entrust their firstborn children to God through immolation.…Now clearly God loves and rewards those sacrifices when a just man endures injustice and struggles for the truth even to the point of death or when he is killed by enemies whom he has offended for righteousness’ sake, as he has returned them good for evil, that is, love instead of hatred.… In imitation of Abel, thousands of martyrs have struggled for the truth to the point of death and have been sacrificed by savage enemies. The Scripture says of them, “God has tested them like gold in a furnace and he has accepted them as a whole burnt offering.” So too the apostle says, “I am being sacrificed.”13
But that is not how Jephthah made a whole burnt offering to the Lord out of his daughter. Rather he offered her as a literal sacrifice in the way that it was commanded for animals to be offered and forbidden for humans to be sacrificed. What he did seems rather similar to what Abraham did. In that instance the Lord gave him a special command that this ought to be done. He did not order him by way of a general commandment that such sacrifices should take place at some time. Indeed, the general rule prohibited it.
