Judges 21:16-18

16Then the elders of the congregation said, “What should we do about wives for those who remain, since the women of Benjamin have been destroyed?” 17They added, “There must be heirs for the survivors of Benjamin, so that a tribe of Israel will not be wiped out. 18But we cannot give them our daughters as wives.”

For the Israelites had sworn, “Cursed is he who gives a wife to a Benjamite.”
