Judges 20:2; Judges 21:5

2 And the chief of all the people, even of all the tribes of Israel, presented themselves in the assembly of the people of God, four hundred thousand footmen that drew sword.

5 And the children of Israel said, Who is there among all the tribes of Israel that came not up with the congregation unto the LORD? For they had made a great oath concerning him that came not up to the LORD to Mizpeh, saying, He shall surely be put to death.
