'Unit' in the Bible

Then Gaal spoke again, “Look, people are coming down from the central part of the land, and one unit is coming from the direction of the Diviners’ Oak.”

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.
