Judges 21:16-18

16Then the elders of the congregation said, “What are we to do for wives for those who are left, since the women have been eliminated from Benjamin?” 17And they said, “There must be an inheritance for the survivors of Benjamin, so that a tribe will not be wiped out from Israel. 18But we cannot give them wives from our daughters.” For the sons of Israel 1had sworn, saying, “Cursed is he who gives a wife to Benjamin!”
