'Men of War' in the Bible

And this is the reason why Joshua did circumcise: All the people that came out of Egypt, that were males, even all the men of war, died in the wilderness by the way, after they came out of Egypt.

For the children of Israel walked forty years in the wilderness, till all the people that were men of war, who came out of Egypt, were consumed, because they obeyed not the voice of the LORD: unto whom the LORD swore that he would not show them the land, which the LORD swore unto their fathers that he would give us, a land that flows with milk and honey.

And you shall march around the city, all you men of war, and go round about the city once. Thus shall you do six days.

And it came to pass, when they brought out those kings unto Joshua, that Joshua called for all the men of Israel, and said unto the captains of the men of war who went with him, Come near, put your feet upon the necks of these kings. And they came near, and put their feet upon the necks of them.
