Judges 21:5

And the children of Israel said, realizing that there might be a way out of their difficulty, Who is there among all the tribes of Israel that came not up with the congregation unto the Lord, to take part in this campaign of vengeance? For they had made a great oath, which included the threat of death upon every one that did not appear, concerning him that came not up to the Lord at Mizpeh, saying, He shall surely be put to death.
