1 Now the men of Israel had sworn in Mizpeh, saying, There shall not any of us give his daughter unto Benjamin to wife. 2 And the people came to the house of God, and abode there till even before God, and lifted up their voices, and wept sore; 3 And said, O LORD God of Israel, why is this come to pass in Israel, that there should be to day one tribe lacking in Israel? 4 And it came to pass on the morrow, that the people rose early, and built there an altar, and offered burnt offerings and peace offerings. 5 And the children of Israel said, Who is there among all the tribes of Israel that came not up with the congregation unto the LORD? For they had made a great oath concerning him that came not up to the LORD to Mizpeh, saying, He shall surely be put to death. 6 And the children of Israel repented them for Benjamin their brother, and said, There is one tribe cut off from Israel this day. 7 How shall we do for wives for them that remain, seeing we have sworn by the LORD that we will not give them of our daughters to wives? 8 And they said, What one is there of the tribes of Israel that came not up to Mizpeh to the LORD? And, behold, there came none to the camp from Jabesh-gilead to the assembly. 9 For the people were numbered, and, behold, there were none of the inhabitants of Jabesh-gilead there. 10 And the congregation sent thither twelve thousand men of the valiantest, and commanded them, saying, Go and smite the inhabitants of Jabesh-gilead with the edge of the sword, with the women and the children. 11 And this is the thing that ye shall do, Ye shall utterly destroy every male, and every woman that hath lain by man. 12 And they found among the inhabitants of Jabesh-gilead four hundred young virgins, that had known no man by lying with any male: and they brought them unto the camp to Shiloh, which is in the land of Canaan. 13 And the whole congregation sent some to speak to the children of Benjamin that were in the rock Rimmon, and to call peaceably unto them. 14 And Benjamin came again at that time; and they gave them wives which they had saved alive of the women of Jabesh-gilead: and yet so they sufficed them not. 15 And the people repented them for Benjamin, because that the LORD had made a breach in the tribes of Israel. 16 Then the elders of the congregation said, How shall we do for wives for them that remain, seeing the women are destroyed out of Benjamin? 17 And they said, There must be an inheritance for them that be escaped of Benjamin, that a tribe be not destroyed out of Israel. 18 Howbeit we may not give them wives of our daughters: for the children of Israel have sworn, saying, Cursed be he that giveth a wife to Benjamin. 19 Then they said, Behold, there is a feast of the LORD in Shiloh yearly in a place which is on the north side of Bethel, on the east side of the highway that goeth up from Bethel to Shechem, and on the south of Lebonah. 20 Therefore they commanded the children of Benjamin, saying, Go and lie in wait in the vineyards; 21 And see, and, behold, if the daughters of Shiloh come out to dance in dances, then come ye out of the vineyards, and catch you every man his wife of the daughters of Shiloh, and go to the land of Benjamin. 22 And it shall be, when their fathers or their brethren come unto us to complain, that we will say unto them, Be favourable unto them for our sakes: because we reserved not to each man his wife in the war: for ye did not give unto them at this time, that ye should be guilty. 23 And the children of Benjamin did so, and took them wives, according to their number, of them that danced, whom they caught: and they went and returned unto their inheritance, and repaired the cities, and dwelt in them. 24 And the children of Israel departed thence at that time, every man to his tribe and to his family, and they went out from thence every man to his inheritance. 25 In those days there was no king in Israel: every man did that which was right in his own eyes.
[AD 397] Ambrose of Milan on Judges 21:1
What regard for virtue our forefathers had to avenge by a war the wrongs of one woman which had been brought on her by her violation at the hands of profligate men! No, when the people were conquered, they vowed that they would not give their daughters in marriage to the tribe of Benjamin! That tribe had remained without hope of posterity, had they not received leave of necessity to use deceit. And this permission does not seem to fail in giving fitting punishment for violation, since they were only allowed to enter on a union by a rape, and not through the sacrament of marriage. And indeed it was right that they who had broken another’s intercourse should themselves lose their marriage rites.

[AD 397] Ambrose of Milan on Judges 21:2-7
The end of the war was also the end of their wrath, and anger turned to sorrow. Then, putting off their armor, the men of Israel met together and wept much and celebrated a fast, grieving that one tribe of their brothers had perished and a strong band of people had been wiped out. They had warred rightly against the authors of the crime because of the cost of the sin, but the people had turned unhappily against their own flesh and each was afflicted with civil war. The outpouring of tears moved their minds to compassion and stirred their feelings; the plan conceived in anger was gone. Sending legates to the six hundred men of Benjamin, who for four months guarded themselves on the top of sheer rocks and by the desert’s barrenness, which was dangerous for a mass of attackers, they lamented their common hardship in losing their fellow tribesmen, relatives and allies. Yet the hope of renewing the tribe was not utterly destroyed, and they consulted together how they might agree on a pledge of faith and one tribe not perish, severed from the body.

[AD 397] Ambrose of Milan on Judges 21:17-21
The sentence, further, was that none of the people of the ancestors should give his daughter in marriage to [members of Benjamin’s tribe]. This was confirmed by a solemn oath. But relenting at having laid so hard a sentence on their brothers, they moderated their severity so as to give them in marriage those maidens that had lost their parents, whose fathers had been slain for their sins, or to give them the means of finding a wife by a raid. Because of the villainy of so foul a deed, they who had violated another’s marriage rights were shown to be unworthy to ask for marriage. But for fear that one tribe might perish from the people, they connived at the deceit.

[AD 379] Basil of Caesarea on Judges 21:25
After a long time spent in this state of indecision and while I was still busily searching for the cause I have mentioned, there came to my mind the book of Judges, which tells how each man did what was right in his own eyes and gives the reason for this in these words: “In those days there was no king in Israel.” With these words in mind, then, I applied also to the present circumstances that explanation which, incredible and frightening as it may be, is quite truly pertinent when it is understood; for never before has there arisen such discord and quarreling as now among the members of the church in consequence of their turning away from the one, great and true God and only King of the universe. Each person, indeed, abandons the teachings of our Lord Jesus Christ and arrogates to himself authority in dealing with certain questions, making his own private rules and preferring to exercise leadership in opposition to the Lord to being led by the Lord.
