'Single' in the Bible

Barak pursued the chariots and the army as far as Harosheth of the Nations, and the whole army of Sisera fell by the sword; not a single man was left.

The LORD told him, "Because I'll be with you, and you'll defeat Midian every single one of them!"

Then the entire army stood up as a single unit and declared, "Nobody's going back to his tent, and nobody's going home!

That's how the army of Israel came to be gathered together to attack the city, united as a single unit.
