Judges 21:16-18

16So the elders of the assembly asked, “How can we find wives for the few who remain, since the women of the tribe of Benjamin are dead?

17There must be heirs for the survivors so that an entire tribe of Israel is not wiped out.

18But we cannot give them our own daughters in marriage because we have sworn with a solemn oath that anyone who does this will fall under God’s curse.”
