'As One Man' in the Bible

The LORD said to him, "Surely I will be with you, and you shall strike the Midianites as one man."

Then all the children of Israel went out, and the congregation was assembled as one man, from Dan even to Beersheba, with the land of Gilead, to the LORD at Mizpah.

All the people arose as one man, saying, "None of us will go to his tent, neither will any of us return to his house.

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