Judges 21:16-18

16Then the elders of the congregation said, “What shall we do for wives for those [men] who are left, since the women of Benjamin have been destroyed?”

17They 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 had sworn [an oath], “Cursed is he who gives a wife to [a man from the tribe of] Benjamin.”
