Judges 20:2, 8, 11

The leaders of all the people and all the tribes of Israel—400,000 warriors armed with swords—took their positions in the assembly of the people of God.

And all the people rose to their feet in unison and declared, “None of us will return home! No, not even one of us!

So all the Israelites were completely united, and they gathered together to attack the town.
