Judges 21:16-18

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