'Men of War' in the Bible

This is the reason why Joshua circumcised them: all the people who came out of Egypt who were males, all the men of war, had died in the wilderness along the way after they left Egypt.

For the Israelites walked forty years in the wilderness, until all the nation, that is, the men of war who came out of Egypt, died because they did not listen to the voice of the Lord; to them the Lord had sworn [an oath] that He would not let them see the land which He had promised to their fathers to give us, a land [of abundance] flowing with milk and honey.

Now you shall march around the city, all the men of war circling the city once. You shall do this [once each day] for six days.

Now the Lord said to Joshua, “Do not fear or be dismayed (intimidated). Take all the men of war with you and set out, go up to Ai; see, I have given the king of Ai, his people, his city, and his land into your hand.

When they brought these kings out to Joshua, Joshua called for all the men of Israel, and told the commanders of the men of war who had gone with him, “Come up close, put your feet on the necks of these kings.” So they came forward and put their feet on the necks [of the five kings].
