Judges 21:4-14

4 The next day the people got up early, built an altar and offered burnt offerings and peace offerings.
5 The people of Isra'el asked, "Who among the tribes of Isra'el did not come up to assemble before ADONAI? For they had made a great oath to put to death whoever didn't come up to ADONAI at Mitzpah.
6 The people of Isra'el became sorry for Binyamin their brother and said, "Today one tribe has been cut off from Isra'el.
7 How are we going to obtain wives for those who remain alive, since we've sworn by ADONAI that we won't let our daughters marry them?"
8 Then they asked who from the tribes of Isra'el had not come up to ADONAI at Mitzpah and found that none had come from Yavesh-Gil'ad to the camp where the assembly was;
9 since when the people were counted, none of the inhabitants of Yavesh-Gil'ad were found there.
10 So the gathering sent 12,000 warriors there and ordered them, "Go, and put the people who live in Yavesh-Gil'ad to death with the sword, including women and children.
11 Completely destroy every man and every woman who has had sex with a man."
12 Among the inhabitants of Yavesh-Gil'ad they found 400 young virgins who had not known a man by lying with him, and they brought them to the camp at Shiloh, which is in the land of Kena'an.
13 Then the whole gathering sent a message proclaiming peace to the people of Binyamin who were at the Rock of Rimmon.
14 So Binyamin returned at that time, and the people of Isra'el gave them the women they had kept alive of the women from Yavesh-Gil'ad. But those weren't enough for them.
