Judges 21:12-16

And they found among the inhabitants of Jabesh-gilead four hundred young virgins who had not known a man by sleeping with him; and they brought them to the camp at Shiloh, which is in the land of Canaan.

Then the whole congregation sent word and spoke to the sons of Benjamin who were at the rock of Rimmon, and proclaimed peace to them.

And the tribe of Benjamin returned at that time, and they gave them the women whom they had allowed to live from the women of Jabesh-gilead; but they were not enough for them.

And the people were sorry for Benjamin, because the Lord had created a gap in the tribes of Israel.

Then 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?”
