'As One Man' in the Bible

The Lord answered him, “I will certainly be with you, and you will strike down the Midianites as [if they were only] one man.”

Then all the sons of Israel from Dan [in the north] to Beersheba [in the south], including the land of Gilead came out, and the congregation assembled as one man to the Lord at Mizpah.

Then all the people stood [unified] as one man, saying, “None of us will go to his tent, and none of us will return to his home [until this is settled].

So all the men of Israel assembled against the city, united as one man.
